Answer:
both males and females
Explanation:
The sex chromosomes in male and female humans are X and Y chromosomes. X-linked traits are those traits which are associated with the X- chromosome.
According to the question, the trait is passed on a X-linked dominant condition, which means that the possession or not of the condition is dependent on the presence of the dominant X-chromosome. The dominant X-chromosome will always express itself even when in an heterozygous state with a normal X-chromosome i.e Xx. Hence, only a individual recessive for the X-chromosome will be normal.
A mother that is affected by the X-dominant condition will either possess a; XX or Xx genotype while a father that is normal (not affected) will possess a (xY) genotype. Since the mother passes one of her X chromosomes to her sons and the other to her daughters, both male and female children will be affected by the condition.
N.B: If the mother is heterozygous for the affected X-chromosome (Xx), half of her sons and half of her daughters will inherit the condition but if the mother contains two dominant X-chromosomes (XX), all of her sons and daughters will inherit the condition.
Intrinsic factor A. increases gastric motility. B. causes the release of stomach acid. C. facilitates the absorption of vitamin B12. D. protects the stomach lining from the effects of stomach acid. E. stimulates the synthesis of DNA.
Answer:
C. facilitates the absorption of vitamin B12.
Explanation:
The Intrinsic factor is a substance that is produced by the stomach and it has the important function of producing vitamin B12 which is necessary for life. Vitamin B12 is used in the production of mature red blood cells. It also improves the function of the nervous system. The production of this intrinsic factor is a very vital role of the stomach because, in the absence of a stomach, for example, in the case of a gastrectomy, a person can only survive if he is given injections of Vitamin B12.
The stomach also serves as a holding center for food and eventually delivers the food to the small intestine and the duodenum.

Explanation:
Match each part of Sammi's model to the bodily structure it represents. One bodily structure has already been labeled for you.
Answer:
corrugated cardboard tube - digestive tract
irregular surfaces on the corrugated tube - villi
pump - heart
Plastic tubing - blood vessels
Explanation:
The corrugated cardboard tube represents the digestive tract. The give away was the presence of the irregular surfaces within the tubes. This is called the villi. The villi is responsible for the absorption of food after digestion into the body.
Irregular surfaces on the corrugated tube represent the villi. They are tiny hair-like structures that are in the small intestine, that are responsible for the absorption of food into the bloodstream.
The pump represents the heart. The heart is the only organ in the body that provides the pressure force that pushes the blood throughout the body. In this model, the pump will most likely be performing the same function.
The plastic tubings are meant to contain one form of fluid or the other. Judging from that, they can be said to represent the blood vessels. This is because they are connected to the heart and are meant to transport bodily fluids around the body

Which scientific questions can be disproved by conducting tests? Select all that apply. Do video games negatively impact mental health? Will my published scientific paper be successful? Can monkeys communicate with each other? Are dogs the most responsible type of pet? Are vegetables good for growing strong bones?
Answer:
Do video games negatively impact mental health?
Are vegetables good for growing strong bones?
Explanation:
A scientific question is one that can be subjected to experimental verification. Experimentation is then used to obtain valid data which can be used to answer the question.
A good scientific question must contain a dependent and an independent variable. The independent variable is manipulated and its effect on the dependent variable is observed.
In the two options chosen;
Effect of video games on mental health can be observed by conducting a research experiment on people who play video games and those who do not play video games.
Effect of vegetables on strong bones can be studied by conducting a research experiment using people who eat vegetables and those who do not eat vegetables.
QUICKLY! The chemical reaction equation of photosyntesis is shown here: What information is not given in this equation. It does not show if the reaction is reversible. It does not show the reactants needed for the reaction. It does not show that photosynthesis consists of many separate steps. It does not show the number of molecules required to produce glucose.
Answer:
C: It does not show that photosynthesis consists of many separate steps.
Explanation:
Photosynthesis is a unique process carried out by the cells of autotrophic organisms. It is the process whereby they synthesize their own food in form of sugars (glucose) in the presence of sunlight. Ideally, the photosynthetic process makes use of carbon dioxide (C02) and water (H20) in the presence of light energy (from sun) to produce glucose sugar (C6H12O6) and oxygen (02). The general photosynthetic equation is as follows:
6CO2 + 6H20 + light → C6H12O6 + 6O2
However, the process is not as simple as portrayed as it involves many separate steps that collectively forms the photosynthetic product (glucose). Photosynthesis occurs in two major stages namely: light stage and light independent stage, which in turn consists of series of reactions that forms the products.
Therefore, the equation attached to this question describes photosynthesis but It does not show that photosynthesis consists of many separate steps.
Answer:
C: It does not show that photosynthesis consists of many separate steps.

When chyme enters the duodenum, ____ is released and stimulates the pancreas to secrete bicarbonates. A. gastrin B. secretin C. insulin D. cholecystokinin E. glucagon
Answer: B. secretin
Secretin is secreted in response to acid in the duodenum, which occurs when acid-laden chyme from the stomach flows through the pylorus. The effect of secretin on the pancreas is to stimulate duct cells to secrete water and bicarbonate.
if the sequence of bases on the mrna codon is auu what would be the sequence of bases on the trna anticodon
att
uaa
taa
uua
Answer:
uaa
Explanation:
An anticodon is a trinucleotide sequence localized in the transport RNA (tRNA) that binds via complementary base pairing to the codon in the messenger RNA (mRNA) during protein synthesis (translation). Thus, the tRNA anticodon binds with its complementary three-letter mRNA codon during translation in order to add a specific amino acid to the growing protein. Generally, the anticodon sequence positions 34–36-nt of the tRNA that reads its cognate mRNA codon sequence via Watson–Crick base pairing.
Which of the following is an example of a non-mendelian pattern of inheritance? A) all traits are inherited through patterns found by Mendel.

C) when pea plants that are hetero-zygous for a certain trait cross some of the offspring express both distinct versions of the trait. D) when horses that are homo-zygous for red hair are crossed with horses that are homo-zygous for white hair, the offspring have both red and white hair.
HEEELLLPPP PLSS!!! Compare and contrast open, closed, and isolated systems. Be sure to discuss the exchange of energy and exchange of matter, and provide at least one example of each.
Answer:
See the answer below
Explanation:
An open system is a type of thermodynamic system in which energy and matter are being exchanged between the system and the surrounding. It is like boiling soup in an open pot. The opening allows for the addition of materials (matters) into the soup and energy is exchanged through the heating. A good example is found in biological organisms. They consume matters and exchange energy with the environment by carrying out work.
A closed system is a type of system in which there is no exchange of matter between it and the environment. However, there is an exchange of energy. It is like boiling water in a closed pot. Nothing can be added into the pot due to the closure but energy can be transferred through the heating of the pot.
An isolated system allows for neither energy nor matter exchange with the surrounding. It is like a closed food warmer that allows for nothing to enter or leaves it.
Answer: Open systems are energy that can be transferred between the system and its surroundings. Close systems are systems that do not transferred to its surroundings. Isolated systems is a thermodynamic system which cannot exchange either energy or matter from outside its boundaries of the system.

A student hypothesized that EC growth might be affected by the DNA from circulating erythrocytes. Is this student’s hypothesis reasonable?
Answer:
Explanation:
It can be said that this hypothesis is actually not reasonable because circulating erythrocytes do not contain DNA. This can be proven by the Mammalian erythrocytes (rbcs) which ultimately loose their nuclei as well as many other organelles during their maturation process and they don't have nuclei or mitochondria meaning that they are not affected by the DNA.

Taxonomists today tend to group organisms into the same category based on similar what?
Answer:
characteristics
Explanation:
oranisms are grouped based on shared characteristics
Taxonomists today tend to group organisms into the same category based on their evolutionary history and shared ancestry, as explained in Option A, as this allows taxonomists to construct more accurate and detailed phylogenetic trees.
What is taxonomy?The field of taxonomy is concerned with the classification of living organisms based on their shared characteristics, the aim of taxonomy is to group organisms in a way that reflects their evolutionary history and to provide a standardized system of naming, while earlier taxonomists relied on morphological characteristics, such as the physical appearance of an organism, but modern taxonomists instead use molecular and genetic data to group organisms into categories.
Hence, taxonomists today tend to group organisms into the same category based on their evolutionary histories and shared ancestry, as explained in Option A.

In the panda case study, we know that here lemming is a small mammal with the very high daily energy expenditure for its size so as per this predict about the lemming that there would not be an affect since the human body does not need any fat and the small intestine would not be able to absorb fats.
Describe Dr. Vellend's unifying theory of ecological communities (the factors that determine community structure). Where do concepts like competition, predation, habitat suitability, disease and parasitism, and disturbance (most of what we covered this semester) fit into his theory
Answer and Explanation:
Community ecology is a discipline that studies the organism's communities and the manner in which populations of species interact with each other within a particular habitat. Mark Vellend is an eco-evolutionist that developed a theoretical framework of ecological communities from a unified functional perspective. This theory is based on four forces of evolutionary biology: selection, drift, dispersal and speciation. This theory is used to explain how species interactions including parasitism, competition and predation may influence population fluctuations. On the other hand, this theoretical framework can also be used to understand how colonization, disturbance and habitat suitability components alter the dynamics of interacting species.

Answer: Zinc is non renewable.
Explanation:
Non-Renewable resources are resources that cannot be replenished easily through natural process. These are the sources which are used in wise manner so that they do not get depleted. For example: coal, petroleum etc.
Renewable resources are resources that can be replenished overtime through natural process.These are the sources which never depletes completely. For example: bio mass energy, solar energy etc.
As zinc cannot be replenished easily through natural process, it is non renewable.
The original name for Asian Homo erectus was Group of answer choices Homo rudolfensis. Australopithecus. Paranthropus. Pithecanthropus.
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).

You have been assigned a DNA stretch. What is the complementary strand when you replicate the template
Answer:
The complementary strands of a DNA are read in the opposite direction to one another
Explanation:
A DNA strand/stretch can be represented with a number of bases. The bases in a DNA strand are Adenine (A), Thymine (T), Cytosine (C) and Guanine (G). The Adenine can bind to Thymine (and vice-versa) while the Guanine can bind to Cytosine (and vice versa). These bonded bases are called "base pairs".
Complementary DNA strands are read in opposite direction to one another. Each end of a DNA strand is either a 5' end or a 3' end. Hence, if one strand runs from the 5' to 3' end, the complementary strand will run from the 3' to 5'. Thus, they are represented "on paper" the way they run.
For example,
If the DNA strand assigned is AGTCTAG running 5' to 3', the complementary strand will be CTAGACT (starting from the 3' end) and NOT TCAGATC (which starts from the 5' end)
