Seeds are reproductive or not ?
Answers
Answer: Yes
Explanation: Monocots produce one cotyledon, while dicots produce two. Because seeds are reproductive structures and thus important to a species' survival, plants have evolved many mechanisms to ensure their survival. One such mechanism is seed dormancy. Dormancy comes in two forms: seed coat dormancy and embryo dormancy
Answer:Plants that reproduce by seeds. Seed plants have special structures on them where male and female cells join together through a process called fertilisation. After fertilisation, a tiny plant called an embryo is formed inside a seed.
Sickle-cell disease is caused by a recessive allele. Roughly one out of every 400 African Americans (0.25%) is afflicted with sickle-cell disease. Use the Hardy-Weinberg equation to calculate the percentage of African Americans who are carriers of the sickle-cell allele. (Hint: q^2 = 0.0025)
Answers
Using the Hardy-Weinberg equation approximately 9.5% of African Americans are carriers of the sickle-cell allele.
The Hardy-Weinberg equation is:
p^2 + 2pq + q^2 = 1
Where p^2 represents the frequency of the homozygous dominant genotype, 2pq represents the frequency of the heterozygous genotype, and q^2 represents the frequency of the homozygous recessive genotype.
Given that sickle-cell disease is caused by a recessive allele, q^2 represents the frequency of the homozygous recessive genotype. We know that one out of every 400 African Americans (0.25%) is afflicted with sickle-cell disease, so q^2 = 0.0025.
We can solve for q by taking the square root of q^2: q = sqrt(0.0025) = 0.05
Now we can solve for p, which represents the frequency of the dominant allele: p = 1 - q = 1 - 0.05 = 0.95
Finally, we can use the equation to solve for the frequency of carriers, which is represented by 2pq:
2pq = 2 x 0.95 x 0.05 = 0.095
Therefore, approximately 9.5% of African Americans are carriers of the sickle-cell allele.

The Atlantic puffin feeds on several species of Atlantic fish. A population of puffins living on Matinucus Rock was found to feed on the types of fish shown in the graph below. The beaks of this group of puffin are shaped to grasp Species A particularly well. Predict what would happen to the puffins’ beaks if another predator enters the area that is better at preying on Species A. Explain your reasoning based on what you know regarding genetic adaptations.
Answers
The number of Atlantic puffins that have adapted to species A will decrease as competition for species A increases. After several generations, the puffins that eat species B and C will be formed.
What is adaptation?
Adaptation is the process of changing in response to a changing environment. An example is seen in puffins. The puffin that eats species A has a different beak. When another predator enters who preys upon species A, then competition will increase. As a result, species A's consumption of puffin will decrease.
Those puffins that eat species B and C will survive. They will reproduce and produce more offspring. The number of puffins with beaks in Species B and C will increase over time.
Hence, after many generations, puffins of species B and C will increase.

C. Addition of TCA
D. All of the options are correct
Answers
Centrifugation is a mechanical process which involves the use of the centrifugal force to separate particles from a solution according to their size, shape, density, medium viscosity and rotor speed.
Trichloroacetic acid (TCA) precipitation of proteins is commonly used to concentrate protein samples or remove contaminants, including salts and detergents, prior to downstream applications such as SDS-PAGE or 2D-gels. TCA precipitation denatures the protein, so it should not be used if the protein must remain in its folded state (e.g., if you want to measure a biochemical activity of the protein).
Determining the protein concentration in your sample is an important step in any laboratory workflow that involves protein extraction and/or analysis. Knowing how much protein you have can help you compare results from one protein to another and from one experiment to the next.

explain how some substances cross the cell membrane by facilitaded diffusion
Answers
According to the research, the correct answer is some substances cross the cell membrane by facilitated diffusion through the use of transporters or carriers.
What is facilitated diffusion?It is a type of transport that requires carrier proteins or transport proteins that are usually located in the membrane.
In this sense, it is used by uncharged water-soluble molecules or charged particles since, due to their water solubility, they are not able to freely cross the lipid bilayer by simple diffusion.
Therefore, we can conclude that facilitated diffusion uses specific membrane transport proteins that allow certain charged molecules to cross the cell membrane.

Describe the 3 kinds of blood vessels.
Answers
Answer:
Type of vessels:
1) Veins: return blood back toward the heart.
2)Arteries: transport blood away from the heart.
3)Capillaries: surround body cells and tissues to deliver and absorb oxygen, nutrients, and other substances.
There are three kinds of blood vessels, they are arteries, veins and capillaries.
Blood vessels are the routes through which blood flows all across your body. They create a circuit-like virtuous cycle that starts and finishes at your heart. Our cardiovascular system is made up of blood vessels and heart vessels. There are approximately 60,000 miles of blood veins in your body.
Blood vessels are of three types: arteries, veins, and capillaries. Each of them performs a distinct role in the circulation process.
Arteries: Arteries are vessels that transport oxygenated blood out from the heart. Although they have a tough exterior, they have a smooth internal layer of epithelial cells that facilitates the easy flow of blood. Moreover, arteries have a thick, muscular middle layer that aids in pumping blood throughout the body.
Veins: Veins transport blood back to the heart. They resemble arteries but aren't strong or thick. Veins, in contrast to arteries, have valves that guarantee that blood only travels in one way. (Arteries don't need valves since blood can only flow in one direction due to the heart's tremendous pressure.) Valves also assist blood in defying gravity and returning to the heart.
Capillaries: Capillaries are the vessels that connect arteries and veins. The arteries transport oxygen-rich blood to the capillaries, where the exchange of oxygen and carbon dioxide takes place. The veins then carry the waste-rich blood back to the heart and lungs through the capillaries.
