chimpanzee
frog
0 The skeletal structure of the gorilla and chimpanzee suggest a common evolutionary ancestry.
The dog and frog share a closer evolutionary ancestry than the gorilla and chimpanzee.
The dog is more closely related to the frog than it is to the chimpanzee.
All four organisms share a common vertebrate ancestor.
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

The complete oxidation of one glucose molecule yields 30 or more ATP . Glucose catabolism includes glycolysis, pyruvate oxidation, and the citric acid cycle. The total yield of ATP includes ATP , GTP , and reduced cofactors that yield ATP from the electron transport chain and oxidative phosphorylation. Which processes yield the most ATP
Answer:
Electron transport chain.
Explanation:
Electron transport chain is the process which yield the most number of ATP as compared to all three major phases of cellular respiration. Glycolysis produces only 2 ATP from the breakdown of molecule of glucose. In the Krebs cycle, one GTP which is an ATP equivalent is produced from the breakdown of one glucose molecule while on the other hand, 32 ATP molecules are produced from the breakdown of one glucose molecule.
If a physicist performs an experiment, who would likely try to replicate it?

Lymph ______ are found throughout the body and are a signal of a disease, infection, or problem if they become and remain swollen for long periods of time.
______ are pathogens that cannot be killed with antibiotics because they are non-living. They take over cellular organelles to replicate and spread.
Because they are also eukaryotes with their own cell membranes and membrane-bound organelles, ______ are often difficult to combat with medicines.
A cell signal called ______ is produced by mast cells. These molecules cause more fluid to spread to an infected area.
_______ are the types of cells that produce antibodies.
All pathogens have unique identifying molecules on their surfaces called ______. Antibodies bind to these, and targeting the pathogen to be destroyed by the immune system.
______ is a non-specific response to disease, in which the body temperature rises
Answer:
nodes
Viruses
fungi
histamine
B-cells
antigens
Fever
When a paper cut breaks the skin, it introduces outside microorganisms into the cut. The body recognizes the break in the skin. Mast cells produce histamines, which cause more blood and lymph fluid to flow to the wound. This increased flow brings phagocytic white blood cells to the area, which destroy invading organisms until the blood can clot and the skin can heal over the cut, preventing more organisms from entering the body. If a cut is too deep or too wide, special care such as stitches and antibiotics could be needed to prevent infection.

Skeletal muscle
Smooth muscle
Cardiac muscle
3
Visceral muscle
A. B. and Care all correct.
Answer:
A, B and C are all correct.
Explanation:
There are three main muscle types:
Muscle skeleton — the specialized tissue that connects to the bones and enables movement. The musculoskeletal system is called skeleton muscles and bones together (also known as the locomotor system). Generally speaking, the biceps and triceps of the front or the back of the upper arm are arranged into opposing pairs. Skeletal muscles are controlled by humans, and so are also called voluntary muscles. Another term is streaked muscles, as the tissue looks streaked on a microscope. smooth muscle -located throughout several internal tissues such as the digestive tract, the uterus, and blood vessels such as the artery. The smooth muscle in layered sheets is placed along the construction length in waves. Another typical word is an involuntary muscle, because, without our knowledge, the motion of the smooth muscle takes place.The cardiac muscle - the heart muscle. Without our conscious awareness the heart contracts and relaxes.
Question 19
How would the carbon cycle be influenced by an increase in aerobic respiration?
Answer:
Cellular respiration does not affect the carbon cycle but is part of the carbon cycle. The 2 carbon cycles. carbon ( C ) is taken up by the plants and trees in the form of carbon dioxide ( CO2 ). Plants converts this CO2 into organic compounds such as glucose ( C6H12O6 ).
Explanation:
Increase in aerobic respiration will lead to increase in the amount of CO2 released into to the atmosphere due to respiration.
Aerobic respiration occurs when oxygen is combined with glucose to yield carbon dioxide and water. This is one of the major ways through which carbon dioxide enters the carbon cycle.
Note that the carbon cycle shows the movement of carbon in nature. Increase in aerobic respiration means that more carbon will be introduced into the atmosphere as carbon dioxide.

A couple owned a fine pure-bread albino female poodle (an autosomal recessive phenotype) and wanted to mate her to produce a litter of white puppies. They took her to a breeder, who said he would mate the female with an albino stud male, also from a pure stock. When six puppies were born, they were all black, so the couple sued the breeder, claiming that he had replaced the stud male with a black dog, producing six unwanted puppies. You are called as an expert witness, and the defense asks you whether it is possible to produce black offspring from two pure-breeding recessive albino parents. What testimony do you give
Answer:
No, it is not possible to produce black offspring from two pure-breeding recessive albino parents. If he would have mated the female with a white male, the whole progeny should be white.

Which of the following is a characteristic of the plasma membrane?
To protect the cell's internal contents, water is the only substance that can freely pass through the plasma membrane.
Only small molecules are allowed into and out of the cell by the plasma membrane.
Its selective permeability allows certain molecules, such as oxygen and carbon dioxide, to flow freely in and out of the cell while controlling the flow of other molecules.
The structure of the phospholipids forms a stiff protective outer shell around the cell's internal contents.
Answer:
The plasma membrane forms a barrier between the cytoplasm and the environment outside the cell. A main characteristic of the plasma membrane is selective permeability
The following is a characteristic of the plasma membrane: Its selective permeability allows certain molecules, such as oxygen and carbon dioxide, to flow freely in and out of the cell while controlling the flow of other molecules, which is the third option.
What is the importance of the plasma membrane in cells?The plasma membrane acts as a barrier in the cell, controlling the movement of molecules as well as some gases such as oxygen, carbon dioxide, and water that pass through it but not larger and more polar molecules. The importance of this is that it regulates and controls the inflow and outflow of substances such as hormones, etc.

Biological organization extends beyond the organism. Which group of terms would be included beyond organism in the same list
Answer:
This question lacks options, the options are:
A. populations, communities, and ecosystems
B. DNA, RNA, and protein
C. Cells, tissues, and organs
The answer is A
Explanation:
The biological level of organization shows the organized build up of life from cellular level to organismal level. However, this organization goes beyond the organismal level. Individual species of organisms can assemble to form a POPULATION.
Likewise, populations of different species can coexist to form a COMMUNITY. The community of organisms can interact with their abiotic environment to form an ECOSYSTEM.
Therefore, the level of biological organization extends as follows:
populations → communities → ecosystems

ANOVA is a technique that permits the comparison of the equality of means for multiple populations. Thus, 3 means could be compared and a determination of whether or not one of the means is significantly different from others can be made. This technique is extremely useful, but, as is always the case, the application requires a firm understanding of models assumptions. Consider the following scenario. A meticulously determined random sample of 200 observations is taken from a very large population. This data divides into 4 groups or factor levels, and a numerical measure for each observation is recorded. The population distribution of the measure appears to be slightly skewed positive. The 4 groups have the following number of observations 30, 100, 15 and 55. Which of the following statements leads to the greatest concern in using ANOVA as an analytical technique.
a. Unequal sample sizes among groups can seriously affect the power of the test.
b. Slightly skewed positive distribution of population measures seriously affect the power of the test.
c. In this scenario, I should be concerned about whether the data has been gathered in a biased fashion.
d. Four is not a sufficient number of groups into which to divide the data.
Answer:
c. In this scenario, I should be concerned about whether the data has been gathered in a biased fashion.
