Answer:
(A) The skeletal structure of the gorilla and chimpanzee suggest a common evolutionary ancestry.
Explanation:
The vertebrate and many of the other parts of the skeletal structure of the gorilla and chimpanzee are alike. (and, by using a little background knowledge, you can figure this out by thinking; if humans share 98% of DNA with chimpanzees and about 96% of DNA with gorillas, then the two animals must share a lot of DNA as well.)
I hope this helps !!!
Answer:
1, 3, 4
Explanation:
The gorilla and the chimpanzee have very similar anatomy, so they are closely related.
There is a small resemblance between the dog and the frog, but nowhere close to the one shared with the gorilla and chimpanzee, so NO
the dog IS more closely related to the frog than the chimpanzee since it looks more similar
yes, all of them are vertebrates and therefore share a single vertebrate ancestor

What is the correct order of the levels of organization in animals from smallest to largest?
Answer:
Molecules, cells, tissue, organ, organ system, organism, population, community, ecosystem, and biosphere are in the correct order of the organization's levels.
Explanation:
Molecule: Atoms, the smallest unit of chemical elements are built up of molecules. You can find it in any matter, whether it lives or not. The most fundamental structures of biological creatures are molecules. Biochemistry and molecular biology are two biological fields focused on this level.
Cell: A cell is the basic unit of life. Two types of cells exist plant cells with a stiff cell wall consisting of cellulose molecules and animal cells with a flexible cell membrane. Cell biologists examine problems like metabolism and other structure and functional questions within and between cells.
Tissue: Tissue consists of cells working together to accomplish a goal. Some tissues include muscle, connective tissue, and neural tissue. Examples of biologists working at this level are histologists.
Organ: An organ is a tissue system that works at bigger scales together to perform specified work in the body of an animal. Brain, heart, and lungs are examples of organs. Anatomy is an example of a specialty in biology which concerns this level.
Organ system: An organ system is a group of bodies that work together to fulfill certain activities of the body. Air systems are used to inhale oxygen and release carbon dioxide in animals, for example, by the lungs, respiratory tract, and muscles. The function of the corpus when working jointly is studied by physiologists. Although physiologists can work at any level, they commonly address queries about organ systems.
Organism: An organism is an autonomous and recognized person. The organisms might be single-cell or multi-cell organisms consisting of organisms and organ systems, as well as bacteria, amiable, or creatures. An example of a multi-cellular organism is a human being.

Which is the main light-absorbing pigment for photosynthesis?
O carotene
O chlorophyll
O hemoglobin
O anthocyanin
Answer:
ChlorophyllExplanation:
Chlorophyll, the primary pigment used in photosynthesis, reflects green light and absorbs red and blue light most strongly.
In plants, photosynthesis takes place in chloroplasts, which contain the chlorophyll.
Answer:
B) Chlorophyll
Explanation:
The chloroplasts, which contain the green pigment chlorophyll, are where photosynthesis takes place. Chlorophyll is the pigment that gives plants their distinctive color. It works by collecting the energy in the sunlight that strikes the plant. Because grass requires photosnthesis to create glucose, which is required for growth inside the grass, photosynthesis is critical to life on Earth. As a result, creatures that eat the grass get energy, and so on. As a result, photosynthesis is the mechanism through which energy is introduced into an environment.

The frequency of a lethal allele in a population is greatest when it is: Group of answer choices dominant manifested in infancy recessive co-dominant
Answer:
recessive
Explanation:
A lethal allele is a gene variant associated with a mutation in an essential gene, which has the potential to cause the death of an individual. In general, lethal genes are recessive because these alleles do not cause death in heterozygous individuals, which have one copy of the normal allele and one copy of the allele for the lethal disease/disorder. In recessive lethal diseases, heterozygous individuals are carriers of the recessive lethal allele and can eventually pass the 'defective' allele on to offspring even though they are unaffected; whereas dominant lethal diseases are caused by dominant lethal alleles, which only need to be present in one copy to be fatal. In consequence, the frequency of recessive lethal alleles is generally higher than dominant lethal alleles because they can be masked in carrier individuals. Some examples of human diseases caused by recessive lethal alleles include, among others, Tay-Sachs disease, sickle-cell anemia, and cystic fibrosis.
The frequency of a lethal allele in a population is greatest when it is: C. recessive.
A lethal allele can be defined as an allele that is responsible for the death of a living organism, especially by preventing its development. Thus, a lethal allele causes a complete mortality in the living organism carrying it, in a hom-ozygous condition.
Basically, a lethal allele is recessive in nature because it is expressed in the phenotype of an organism. Some examples of diseases caused by lethal alleles in humans are:
Cystic fibrosisSickle-cell anemiaAchondroplasiaIn conclusion, a lethal allele that is recessive has the greatest frequency in a population.

All theories are hypotheses, but not all hypotheses are theories. Francis wants to know if a specific hypothesis he is researching is a theory. Which describes how Francis would know the hypothesis is a theory?
He could restate the hypothesis as a fact and no longer an explanation.
He could determine whether the hypothesis is based on repeated experiments.
He could perform the experiment and adjust data to match the desired results.
He could design and perform a new controlled experiment to test the hypothesis.
Answer:
He could determine whether the hypothesis is based on repeated experiments.
Explanation:
A theory is a hypothesis that has been proven correct by many expirements.
Francis could design and perform a new controlled experiment to test the hypothesis to determine whether it is a theory. Therefore, the correct statement is option D.
What is a theory?A hypothesis is a scientific explanation for a phenomenon that is based on prior observation. However, a theory is a well-supported and widely accepted explanation for a natural phenomenon that has been tested and based on scientific fact.
A hypothesis has the potential to become a theory if tested through carefully designed and controlled experiments by collecting data needed for the experiment.
If the results of an experiment conducted by Francis are consistent with the hypothesis, the information can be used to develop a theory that can be used to explain a broader range of phenomena. However, if the results are not by the hypothesis, Francis cannot consider the hypothesis as a theory that must be supported by evidence.
Therefore, Francis needs to design and perform a new controlled experiment to test the hypothesis to determine whether it is a theory.

Which of the following is not an example of where primary succession typically occurs?
After a fire
A retreating glacier
Emerging islands
Formation of new lakes
Answer:
After a fire
Explanation:
Primary succession is one of the two types of ecological succession in which a barren area of land (with no soil) is colonized by organisms called PIONEER SPECIES for the very first time.
Primary succession is characterized by a BARREN area that had no form of previous growth or colonization. These barren area can include a retreating glacier, an emerging islands or the formation of new lakes.
Note that, the succession that occurs AFTER A FIRE or any form of environmental disturbance is SECONDARY SUCCESSION.

Answer:

Explanation:
Please name and briefly explain two of the ways meiosis results in genetically unique daughter cells.
Answer:
Recombination and independent assortment.
Explanation:
Recombination and independent assortment in meiosis are the two ways of meiosis that results in genetically unique daughter cells. Recombination is also called crossing over that is the exchange of genetic material that occurs in the germ line. During crossing over, part of one daughter chromosome is exchanged with another that causes diversity whereas independent assortment refers to the allele a gamete receives for one gene does not influence the allele received for another gene.
Which of the following is true of crossing over? It involves the exchange of chromosome segments between homologous chromosomes. It occurs in meiosis I. It increases genetic variability. All of the choices are correct.
Answer: All of the choices are correct.
Explanation:
Meiosis is a type of cell division of the nucleus that occurs in cells that will give rise to gametes (egg or sperm). These are haploid cells (n), that is, they possess only one chromosome of each of the pairs (23 in total). Through meiosis from a diploid cell (2n), four haploid cells are obtained, thanks to two successive divisions called meiosis I and meiosis II. Both comprise prophase, metaphase, anaphase and telophase.
Homologous chromosomes are a pair composed of a paternal and a maternal chromosome. They have the same DNA sequence arrangement from one end to the other, but different alleles. These chromosome copies have the same genes at the same loci where they contribute tips along each chromosome that facilitate a pair of chromosomes to align correctly with each other before they separate during meiosis. Sister chromatids are those that make up a chromosome after duplication of the genetic material.
The homologous chromosomes of maternal and paternal origin, mate and this process is called "synapsis" and form what is known as a tetrad or bivalent chromosome, giving the impression that it is a chromosome with four chromatids. In these tetrads, junctions called chiasmata are formed, areas in which both homologues exchange genetic material or genes, a process known as crossing-over. The chiasmata allow the chromosomes to be held together until their separation in anaphase l. So, genetic recombination is the process by which a segment of genetic material from a maternal chromosome is cut and then joined to a paternal chromosome (or vice versa) during prophase I of meiosis. So it happens between non-sister chromatids of a paternal and a maternal chromosome.
After crossing over, the homologous chromosomes are arranged randomly at the cell's the equator of the cell at random (methaphase), facing each other, still united in the areas where crossing over occurred. Each chromosome is associated with a meiotic spindle fiber of the meiotic spindle and they are pulled along the meiotic spindle and driven toward the respective poles (anaphase). The chromosomes are now arranged at the poles and the reorganization of the nuclear envelope and the nucleolus begins. Finally, cytokinesis occurs and the rearrangement of cellular components and reorganization of the cytoskeleton. As a result of meiosis I, 2 haploid cells are obtained and then meiosis II occurs, where the sister chromatids are separated, generating two more cells (a total of 4).
Genetic variability is generated because the gametes produced during meiosis will not inherit the same chromosomes as the mother cell, but due to crossing over, the inherited chromosomes will be genetically different.
Which structures allow lycophytes to grow bigger than mosses and liverworts?
A. gametophytes and sporophytes
b. xylem and phloem
C. haploid and diploid
D. roots and stems
The structure that allows lycophytes to grow bigger than mosses and liverworts is xylem and phloem which is option B
Lycophytes are spore bearing vascular plants. Being a vascular plant, they possess vessels ( vascular tissues) which include:
ylem: this is used for conducting water usually from the root to the rest of the plant partsPhloem: this is the vascular tissue that is used to conduct food( sugar) produced in the leaves of plants to other parts of the plant.The possession of the vessels makes the lycophytes appear bigger.
Mosses and liverworts belongs to the plant phylum Bryophyta. They do not have any vascular tissues that can be used to conduct water and food. This restricts their size.
