Two genes, CaM and BMP4, control beak ____________ and ____________ , respectively, in finches. High levels of CaM expression will result in ____________ beaks, whereas low levels of CaM expression will result in ____________ beaks. High levels of BMP4 expression will result in ____________ beaks, whereas low levels of BMP4 expression will result in ____________ beaks. Therefore, the degree of expression and, consequently, the amount of ____________ produced, affects beak development in utero. Therefore, small changes to the ____________ within a developing embryo could result in the formation of new species, providing both evidence and a mechanism for ____________ .
Answer:
1. Beak shape and depth
2. Long beaks; short beaks
3. Tall beaks; shallow beaks
4. Protein
5. Genes; macroevolution
Explanation:
Two genes, CaM and BMP4, control beak shape and depth, respectively, in finches. High levels of CaM expression will result in long beaks, whereas low levels of CaM expression will result in short beaks. High levels of BMP4 expression will result in tall or deep beaks, whereas low levels of BMP4 expression will result in shallow beaks. Therefore, the degree of expression and, consequently, the amount of protein produced, affects beak development in utero. Therefore, small changes to the genes within a developing embryo could result in the formation of new species, providing both evidence and a mechanism for macroevolution .
Note:
The BMP4 gene is the gene for Bone morphological protein 4. It determines how deep or tall the beak will be.
The CaM gene is the gene for Calmodulin. It regulates how long a beak will grow.

What structures act as filters to trap pathogens and damaged cells as lymph flows through them?
Answer:
Spleen
Explanation:
The is because the spleen is an organ found in upper section of the abdomen spleen acts as a filterand it help to remove old and damaged cells . It also play a major role in controlling the amount of blood and blood cells that move round the body. The spleen also helps remove pathogens. It contains white blood cells called lymphocytes and macrophages.
What are the two main ways bacteria cause illness?
A. By releasing toxins that poison your cells
B. By using your cells to make copies of themselves
C. By changing the genetic material inside your cells
D. By breaking down your cells for nutrients
Answer:
A. By releasing toxins that poison your cells
B. By using your cells to make copies of themselves
Explanation:
Within the body, bacteria can divide (multiply) and kill host cells by disrupting their normal functioning. Moreover, bacteria secrete toxins that are able to destroy host cells' metabolic machinery. For instance, many bacteria synthesize exoenzymes and interferons that disrupt and destroy host cells. Bacterial toxins can be synthesized internally in order to develop sensitivity through antigenic properties.

Use a Punnett square diagram to show why, for each pregnancy, the chances of giving birth to either a boy or a girl are 50-50. Explain the results shown in your diagram.
Answer:
Because the offspring of a male and female are always going to be xx, xx, xy, or xy.
Explanation:
Remember that men have different reproductive chromesomes than women. Women have 2 x chromesomes(xx) while men have 1 x and 1 y(xy). These are given down to their offspring.
So we can write the this out in a punnet square as(link down below).
After you see the visual, you will find that the genotypes are xx, xx, xy, xy.
As I said above, women have sex chromesomes xx, while men have sex chromesomes xy. When you match the genotypes on the punnet square with the ones we know from men and women, we find that two of them match with men and two match with female.
So with this, we can conclude that 2/4 of offspring will always be male and 2 will be female. And as you well know 2/4 is 1/2 which is 50%.

The disease multiple sclerosis makes it more difficult for signals from the brain and spinal cord to travel along nerve fibers. How will multiple sclerosis
affect other body tissues?
O Connective tissue will increase its fat storage.
O Muscle tissue will contract uncontrollably.
Epithelial tissue will lose the ability to protect against infection.
Tendons and ligaments will become brittle and break.
Answer:
O Muscle tissue will contract uncontrollably.
Explanation:
Multiple sclerosis, also known as encephalomyelitis disseminata, is a disease that affects the brain and spinal cord. Some of the most common symptoms of multiple sclerosis include vision problems, arm or leg movement and balance. This disease occurs when the immune system attacks the myelin sheath that covers nerve cells in the brain and spinal cord, causing inflammation and subsequent damage of the sheath and the nerve fibers it surrounds. Multiple sclerosis may cause muscle twitches when nerve fibers are damaged, thereby disrupting the signaling between nerves and muscles.
Summer is coming and we are ready to get out and get in the sun. However, sun light has some ultraviolet light. When a UV photon is absorbed by a molecule of DNA, there are different ways the energy can be absorbed. One of the ways is that the energy of the photon can be converted into vibrational energy of the molecular bonds. Excessive vibration can damage the molecule by causing the bonds to break. UV light of less than 290 nm causes significant damage to DNA and UV light of longer wavelength causes minimal damage. What is the threshold photon energy, in eV, for DNA damage
Answer:
The threshold photon energy for DNA damage = 4.28 eV
Explanation:
According to the Planck - Einstein's equation, the energy of a photon, E is proportional to its frequency; E = hf where f is frequency and h is Planck's constant.
Also, frequency, f = velocity /wavelength
f = c/λ where c is the velocity of light
E = hc/λ
h = 6.63 × 10^-³⁴ Js;
c = 3.0 × 10⁸ m/s;
Threshold wavelength, λ = 290 nm = 2.9 × 10^-7 m
E = (6.63 × 10^-³⁴ × 3.0 × 10⁸) / 2.9 × 10^-⁷
E = 6.85 × 10^-¹⁹ J
1 ev = 1.602 × 10^-¹⁹ J
6.85 × 10^-¹⁹ J = 6.85 × 10^-¹⁹ J × 1 eV / 1.602 × 10^-¹⁹ J = 4.28 eV
Therefore, the threshold photon energy for DNA damage = 4.28 eV
How many kidneys are in the average
adult human?
Answer:
Two kidneys
Explanation:
Most people have two kidneys, however, it is possible to live a healthy and active life with only one functioning kidney.
An isometric exercise is one in which the joint angle does not change during the application of muscle force. For instance, you can join your hands together, pushing down with one hand and pushing up with the other. In each arm, the muscles that provide the force are connected to the bones of the arm by tendons. If you increase the forces but keep the angles the same, the muscles will still contract. Explain how this is possible.
3. Why is it important to know the customers preference on the product?
g Type I diabetes is caused by destruction of the beta cells of the pancreas, the cells that produce insulin. In most cases, the beta cells are destroyed by an immune response. Both genetic and environmental factors are involved in triggering the immune response. A. The immune system usually does NOT destroy the beta cells. If the cells are destroyed, it is a failure of (memory) (specificity)(tolerance) (any one of these) (none of these).
Answer:
it is a failure of tolerance (self-tolerance) and specificity (recognition)
Explanation:
Type 1 diabetes is a chronic disease caused by the selective destruction of β cells that are involved in the production of insulin in the pancreas. Type 1 diabetes can be classified into two types: Type 1A diabetes (the immune form of the disease) and Type 1B diabetes (the non-immune form of the disease). Type 1A diabetes is considered an autoimmune disorder where immune responses against pathogens suffer a failure of tolerance to antigens in the β-cells of the pancreatic islets. Thus, Type 1A diabetes is characterized by the process of recognition of β-cell antigens (autoantigens) by the immune system. This disease is often caused by genetic factors associated with mutations in the human leukocyte antigen (HLA) class II region located on chromosome 6.

D: Spindle fibers protect the cell from damage during DNA replication.
Answer:
The answer is D
Explanation:
According to the law of conservation of energy, what can happen to the total
energy of a system?
A. The total energy must remain the same, but energy can change
forms and be transferred within the system.

into the system so that they total energy of the system stays the
same.
C. The total energy can decrease when energy is lost due to energy
transformation within the system.
D. The total energy can increase if energy is transferred into the
system from surroundings.
