Answers

Answer 1

Answer: Pithecanthropus erectus.

Explanation:

Between 1891 and 1892 Eugène Dubois believed he had found the "missing link", hypothesized by Ernst Haeckel, when he discovered some loose teeth, a skull cap and a femur - very similar to that of modern man - in the excavations he was carrying out in Trinil, located on the island of Java, Indonesia. Homo erectus erectus was the first specimen of Homo erectus to be discovered.  Dubois first named it Anthropopithecus erectus and then renamed it Pithecanthropus erectus. The name Homo erectus means in Latin "erect man", wich means, "standing man", whereas Pithecantropus erectus means "standing ape-man".

So, Dubois published these findings as Pithecanthropus erectus in 1894, more popularly known as "Java Man" or "Trinil Man". In the 1930s the German palaeontologist Ralpf von Koenigswald obtained new fossils, both from Trinil and from new locations such as Sangiran and in 1938 von Koenigswald identified a magnificent Sangiran skull as "Pithecanthropus". It was not until 1940 that Mayr attributed all these remains to the genus Homo (Homo erectus erectus).

Prader-Willi syndrome is a genetic disorder involving a partial deletion of chromosome 15q on the paternal chromosome. When both copies of a gene (or chromosome) are functional but only one is expressed, this is an example of ________.

Answers

Answer:

monoallelic gene expression

Explanation:

Monoallelic expression is a type of gene expression where only a copy out of the two copies of a gene is expressed and the other is silent.

A gene is usually represented by two alleles representing alternate forms of the same character. Individuals inherit an allele each from their two parents for every gene within their genomes.

When only one of the alleles is expressed for a particular gene while the other allele remains silent, such phenomenon is referred to as monoallelic gene expression.

Centrioles have pulled the chromosomes all the way to the spindle poles, the process of cleavage furrowing appears to be about to begin. What kind of a cell is this?

Answers

Answer:

An animal cell in the telophase

Explanation:

Telophase is one of the stages of cell division in animal cell .

In the animal cell during telophase, Centrioles have pulled the chromosomes all the way to the spindle poles, the process of cleavage furrowing appears to be about to begin because the nuclear membrane and nucleoli reform, cytokinesis is almost coming to completion and the chromosomes eventually uncoil to chromatin. Usually cytokinesis occurs during telophase.

Scientists today are studying tidal power as an alternative energy source for generating electricity. Some scientists conclude that tidal power is a good alternative source of energy because it uses a natural process, does not rely on fossil fuels, and does not release greenhouse gases. These scientists recommend building tidal power plants around the United States in locations with high tidal power potential. Other scientists conclude that tidal power is not a good alternative energy source because tidal power plants can negatively impact the surrounding ecosystem by killing marine animals, restricting fish migration, reducing the natural flow of water, and causing silt buildup in waterways. These scientists recommend not building tidal power plants in U.S. waterways. Both conclusions are based on valid data and scientific reasoning. How can both conclusions be valid?

Answers

Answer:

See the answer below

Explanation:

Both conclusions can be valid because they are based on valid data and scientific reasoning.

In order for a data to be valid in making a conclusion, such data must have been collected through a scientific experiment that is devoid of subjectivism. In order words, the data must have been objectively collected via standard experimental procedures.

Once data have been collected, they are analyzed and used to make valid conclusions based on the hypothesis which must have been made earlier before the experiment.

Conclusions made from standard experimental procedures and scientific reasonings are valid and such experiments are reproducible.

Hence, as long as the data from which the conclusions were made can be reproduced through the same experiments, the conclusions are valid.

Cloning to produce embryonic stem cells is called A) regenerative cloning. B) transplantational cloning. C) reproductive cloning. D) therapeutic cloning. E) dedifferentiation.

Answers

Answer:

D

Explanation:

The correct option would be therapeutic cloning.

First and foremost, cloning refers to the process of producing genetically and phenotypically similar organisms or cells from a single organism/cell, be it naturally or artificially. The genotypically and phenotypically similar copies of the original organism are called clones.

Artificial clonings are of different types, namely:

Reproductive cloningGene cloningTherapeutic cloning

Reproductive cloning has to do with producing genetically identical organisms from a particular organism while gene cloning involves producing exact copies of a gene or segments of DNA. Therapeutic cloning, however, involves the production of embryonic stem cells in order to create tissues that would replace similar but damaged or worn-out tissues in living organisms.

The constant wave action generates nutrients that attract predators. d. The ocean conveyor belt raises and lowers the water levels on the coasts.

Answers

Answer:

b

Explanation:

The correct answer as to the ocean process that exposes the coastal organisms to land-based predators would be the daily tidal patterns that leave the coastal area exposed to the land for a part of the day.

Some parts of the coastal areas become exposed to land during certain periods of the day as a result of tidal waves. When this happens, the aquatic organisms occupying these coastal areas become temporarily exposed to land predators who hunt and kill them for food.

Therefore, the correct option is b.

The pygmy shrew is the smallest mammal in North America. However, when comparing the amount of
food eaten to its body weight, the pygmy shrew eats more food than any other mammal. It will
consume two to three times its own body weight in food daily. One explanation is that the pygmy
shrew uses energy at a high rate. In fact, its heart beats over one thousand times per minute.
What is the best explanation for what happens to the food's mass and energy when it is consumed by
the pygmy shrew?
A. The mass is mostly excreted as waste. The

How Pygmy shrew uses its food for energy?

The pygmy shrew has a large appetite which is a result of small body mass, rapid heat loss and high metabolic rate. It is kept in captivity which provides some idea of ​​the energy requirements of the species.

The pygmy shrew has such a high metabolism that it must eat at least every 30 minutes otherwise it will die. This can be explained by food mass and energy is that due to very high metabolism most of the food mass which is rapidly used up to form shrew, and a large proportion of the food is lost from the body surface because of its very small size.

The combination of these two factors are

1. A very high metabolism which is rapidly utilizes food material, and generates large amounts of heat in a very short period of time.

2. Very small size due to which high surface area to volume ratio leading to heat loss.

Thus, Mass used for growth, stored or excreted as waste. Energy is stored that is used in cellular respiration which is lost to the environment in the form of heat. So, the correct option is (C).

Answers

C. Incomplete dominance.

Explanation:

Incomplete dominance is the blending of alleles. If a plant with red flowers and a plant with white flowers produce offspring, then the flowers will be pink. Red and white mixed together will be pink, the alleles blended.

Codominance is where both traits are present, no blending occurs. If a plant with red flowers and a plant with white flowers produce offspring, the flowers will be both white and red. The flower may be white with red spots, or vice versa. Both alleles are present in the flower.

In this case, it is incomplete dominance, as the offspring is a mix of the parents. The alleles blend and the offspring is pink.

In most organisms, the end product of glycolysis is pyruvate. Pyruvate still contains a substantial amount of energy, which can be further extracted. Whether the organisms are operating under aerobic or anaerobic conditions determines the metabolic pathway that pyruvate undergoes to produce more ATP. In this tutorial, you will identify the end products of these metabolic pathways.

Answers

Answer:

Pyruvate helps in the production of ATP.

Explanation:

The molecule of pyruvate converted into acetyl CoA. Then each molecule which is produced during glycolysis loses electron and carbondioxide releases. After the breakdown of pyruvate, the electrons loses by pyruvate are transferred to NAD+ in order to produce NADH, which will be used by the cell to produce energy molecule such as ATP. So we can say that pyruvate plays a vital role in the formation of ATP molecule.

Which of the following statements is compatible with Darwin’s theory of evolution? much of the variation in individuals of a population is heritable resources are unlimited survival depends mostly on luck members of a population are usually very much alike in their characteristics

Answers

Answer:

A. much of the variation in individuals of a population is heritable

Explanation:

Charles Darwin is a scientist well known for his development of the concept of evolution. Darwin was able to deduce that the species of a population have a common ancestor and that as time passes there is a modification in the characteristics of these species that makes it easier for them to adapt to their environments. These traits that were inherited from past descendants, were helpful traits that made it possible for their own descendants to be able to survive better than their peers. He noted that there were limited resources for survival, therefore it was a case of the survival of the fittest.

Natural selection was the term used by him to describe how species of a population survived over time. Members of a population had varied traits that enabled them to survive. For example, the descendants of an ancestor could have slightly different shapes, colors, sizes, and other features but still maintain traceable heritable traits.

Knowledge of the driver mutations underlying cancer has led to targeted therapeutics, such as the protein kinase inhibitor imatinib (trade name Gleevec) in cases of chronic myeloid leukemia. Cancer cells often become resistant to a given drug, so researchers continue searching for new drugs that target proteins that contribute to the cancerous phenotype. One recent promising approach uses drugs that lead to ubiquitination and proteasomal degradation of the target protein. Which of the following mutated proteins are good candidates for this approach?
A) oncogenes
B) proteins with loss-of-function mutations
C) proteins with gain-of-function mutations
D) tumor suppressor genes

Answers

Answer:

C) proteins with gain-of-function mutations

Explanation:

Gain-of-function mutations: In biology, the term "gain-of-function mutation" is described as one of the different types of mutation in which the altered or changed "gene product" consists of an entirely new pattern or molecular function associated with gene expression. However, the "gene-of-function mutations" are being always considered as "Semidominant or Dominant".

Biochemical and genetic experiments have demonstrated that the _________ of tRNA are important for recognition by its cognate aminotransferase-tRNA synthetase.

Answers

Answer:  Acceptor stem and anticodon loop.

Explanation:

Transfer RNA (tRNA) is a small RNA nucleic acid involved in protein synthesis (translation). Each tRNA molecule has two important areas:

A region of trinucleotides, called the anticodon A region where a specific amino acid binds.

During translation, the ribosome reads the sequence of the mRNA in groups of three bases to assemble the protein. So, in the mRNA chain there are codons, set of three bases, which determine the amino acid to be added to the peptide chain. The tRNA transfers the amino acid to the ribosomes, and then arranges them along the messenger RNA (mRNA) molecule. Then, the tRNA must have an anticodon that is complementary to the codon. Each type of tRNA is specifically combined with 1 of the 20 amino acids to be incorporated into proteins.

This means, during translation, each time an amino acid is added to the growing chain, a tRNA molecule is formed whose base pairs have a complementary sequence with mRNA molecule, ensuring that the appropriate amino acid is inserted into the protein. So, tRNA is a key link between RNA transcription and the translation of that RNA into protein. On the other hand, aminotransferases are enzymes responsible for attaching amino acids to the 3ʹ‐end of cognate tRNAs.

The acceptor stem is the site of attachment of amino acids to tRNA, and anticodon loop is the site of tRNA that is complementary to the codons found in mRNA (that determine the amino acid that will be added) This means, both parts are important for recognition, because the acceptor stem is where the amino acid is, and the anticodon loop ensures that the appropriate amino acid is inserted into the protein.

Explanation:

The spinal nerves include the sensory or motor neurons sensory neuron → brain → motor neuron → muscles.

What are neurons?

Neurons are nerve cells that are specialized to process and transmit information. The brain then processes the information obtained from the sensory neuron and sends another signal trough the motor neuron carrying the message to the muscle.

The spinal cord acts as a nerve center between the brain and the rest of our body and it contains motor neurons that transmits nerve signals from the motor cortex to the body, and the spinal cord also receives all of the sensory information from the periphery of our bodies.

Motor neurons are also known as efferent neurons, they are part of the central nervous system that transmit impulses from the brain or spinal cord to the effector organ (muscles or glands).

Repressorb. Operator c. Promoterd. Corepressore. Inducer

Answers

Answer:

A repressor is a regulatory protein that may bind DNA to inhibit transcription. An operator is a DNA sequence that binds a regulatory protein. A promoter is a DNA sequence that binds RNA polymerase and regulates transcription. A corepressor is a compound that interacts with another protein or compound to form an active repressor. An inducer is a compound that induces or activates transcription, such as lactose.

Explanation:

Repressor proteins bind to DNA and RNA to suppress target gene expression. A DNA repressor blocks transcription by inhibiting the attachment of RNA polymerase to the promoter sequence, while an RNA repressor bind to the mRNA to block translation of the protein. An operator is a DNA sequence required for the attachment of transcription factors. The genes that are transcribed by the binding of a transcription factor to an operator sequence are collectively referred to as an operon. Operons are generally found in prokaryotes but they also can be found in some eukaryotes including Caenorhabditis elegans and Drosophila melanogaster. An inducer is a molecule that activates gene transcription either by binding to repressors/corepressors (thereby inactivating their functions) or by binding activators. For example, the allolactose act as an inducer of the lac operon.
