30. (06.05 mc) suppose a fungus destroys the central xylem and phloem tissues in the roots of a tree. what function of the root system will be lost because of this damage? (2 points)

Answers

The central xylem and phloem tissues in roots play a significant role in transporting water, nutrients, and sugars throughout the plant, respectively.

Xylem tissue is responsible for moving water and minerals from the roots to the rest of the plant, while phloem tissue transports sugars, amino acids, and other nutrients produced by the leaves throughout the plant.In a case where the central xylem and phloem tissues in the roots of a tree are destroyed by a fungus, the transport of water, minerals, and sugars would be hindered, leading to a loss of function of the root system. The plant would not be able to absorb essential nutrients and water from the soil effectively, leading to dehydration and malnutrition. This, in turn, could lead to a decrease in the rate of photosynthesis, growth, and reproduction.

Ultimately, the death of the plant would be inevitable if the damage is not corrected in time. The destruction of the central xylem and phloem tissues in roots by the fungus would have severe consequences on the plant's overall health and survival.

5. which statement regarding double fertilization in angiosperms would lose points on an exam? a) the angiosperm embryo is diploid. b) the pollen tube reaching the micropyle results in the death of one of the synergids. c) the fertilized angiosperm ovule consists of diploid and triploid cells. d) the megasporangium gives rise to four haploid eggs through meiosis. e) one of the pollen nuclei contributes to the genome of the endosperm.

Answers

Double fertilization is a process that occurs in angiosperms (flowering plants) during the fertilization of the ovule. In this process, two fertilizations occur in which one sperm cell fuses with the egg cell to form the zygote while the other sperm cell fuses with the polar nuclei to form the triploid endosperm.

This process is essential for the development of angiosperm seeds and fruits. However, one of the given statements regarding double fertilization in angiosperms would lose points on an exam, which is d) the megasporangium gives rise to four haploid eggs through meiosis. In angiosperms, the megasporangium, also known as the ovule, gives rise to the female gametophyte which contains only one egg cell.

During the process of megasporogenesis, meiosis occurs which produces four haploid megaspores. Out of these four megaspores, only one survives and develops into the mature female gametophyte. Therefore, the statement d) the megasporangium gives rise to four haploid eggs through meiosis is false, and it would lose points on an exam.The correct statement is e) one of the pollen nuclei contributes to the genome of the endosperm. During double fertilization, one of the two sperm nuclei fuses with the polar nuclei to form the triploid endosperm, while the other fuses with the egg to form the diploid zygote.

The angiosperm embryo is diploid, and the pollen tube reaching the micropyle results in the death of one of the synergids. The fertilized angiosperm ovule consists of diploid and triploid cells. Therefore, the correct statement is e) one of the pollen nuclei contributes to the genome of the endosperm.

true or false: people with fatal familial insomnia harbor the prion gene mutation in only the cells of the thalamus. (hint: its a genetic disease passed from generation to generation) group of answer choices true false

Answers

The statement "people with fatal familial insomnia harbor the prion gene mutation in only the cells of the thalamus" is false. Fatal familial insomnia (FFI) is a genetic disease that is passed down through generations. It is caused by a mutation in the PRNP gene that is located on chromosome 20.

The PRNP gene provides instructions for making a protein called prion protein (PrP), which is found mainly in the brain. The mutation results in the production of a misfolded prion protein that causes the death of nerve cells in the brain. This damage is particularly pronounced in a part of the brain called the thalamus.

The thalamus is responsible for regulating sleep, which is why insomnia is a hallmark symptom of FFI. However, the prion protein is found in other cells besides the cells of the thalamus. This includes cells in the spleen and lymph nodes, as well as other parts of the brain. The misfolded prion protein can accumulate in these cells and lead to the development of other forms of prion disease, such as Creutzfeldt-Jakob disease.

Therefore, it is not accurate to say that the prion gene mutation is only found in the cells of the thalamus.

Follicle-stimulating hormone (FSH) and luteinizing hormone (LH) are two hormones that are tested by both partners in a couple that is struggling to conceive a child. The hormones play roles in the ovarian cycle and sperm production. They are typically tested during an infertility evaluation at a fertility clinic.

The ovaries are controlled by FSH, which is produced by the pituitary gland. FSH stimulates the growth of follicles in the ovaries, which contain eggsLH triggers ovulation, which is when the ovary releases an egg. LH also stimulates the production of progesterone by the ovaries, which helps prepare the uterus for implantation of a fertilized egg.

Answers

The lymphatic vessel that collects lymph from the left chest, abdomen, and lower limbs is called the thoracic duct.

The thoracic duct is the largest lymphatic vessel in the body and plays a crucial role in the lymphatic system. The thoracic duct begins in the abdomen, near the second lumbar vertebra, where it collects lymph from the intestinal lymphatic vessels called lacteals. It ascends through the thoracic cavity, alongside the aorta, and collects lymph from various organs and tissues along its course, including the left chest, left arm, left side of the head, neck, and upper thorax. Eventually, the thoracic duct drains into the left subclavian vein near the junction of the left internal jugular vein, returning the lymph back into the bloodstream. This junction is an important site where lymph from the thoracic duct combines with venous blood, allowing the transfer of immune cells and waste products from the lymphatic system to the circulatory system. The thoracic duct serves as a major pathway for the return of lymph and plays a crucial role in maintaining fluid balance, immune response, and nutrient absorption within the body.

tntc - too numerous to count is when the number of colonies on a plate is greater than 300 group of answer choices true false

Answers

True or false: TNTC - too numerous to count is when the number of colonies on a plate is greater than 300?Answer: TrueWhen microbiologists work on microbial cultures, they analyze and evaluate them in different ways. The colony-forming units (CFU) are the most prevalent way to determine the number of bacteria in a sample.

Microbiologists grow bacterial samples on agar plates to separate and determine how many bacterial colonies they can create.Microbiologists use a Petri dish and appropriate culture media to culture microbial cells. A streak plate, a spread plate, or a pour plate is used to isolate and purify a colony of microorganisms.

Colony formation is caused by the multiplication of a single microbial cell. A single cell, called a colony-forming unit (CFU), produces one colony on a plate.Each of the colonies grown on the Petri dish contains millions of identical microbes. To determine how many bacteria are in the initial culture, microbiologists count the number of colonies. The CFU is the number of cells or bacteria in the initial culture, estimated by multiplying the number of colonies by the number of cells that form each colony.

When analyzing microbial cultures, if the colonies are so numerous that they cannot be counted, it is referred to as TNTC - too numerous to count. As a general rule, TNTC is defined as having more than 300 colonies on a plate. Thus, we can say that the given statement is true that TNTC - too numerous to count is when the number of colonies on a plate is greater than 300.

Answers

The change in a coefficient of linkage disequilibrium

(D) equal to -0.204 expected to be if the recombination rate is 0.001  is 0.2041.

The formula for the calculation of D is:

D = pAB - pApB, where:

pAB is the frequency of a haplotype containing alleles A and B, pApB is the expected frequency of a haplotype consisting of the frequencies of A and B alleles based on their individual frequencies. The formula for calculating the expected change in D with a recombination rate of r is:

∆D = -rDIn this question,

the value of D = -0.204 and the recombination rate(r) = 0.001.

We can substitute these values into the above equation to obtain the change in D as follows:

∆D = -rD∆D = -0.001 (-0.204)∆D = 0.000204

Answers

The relationship between the number of offspring produced and the average size of offspring produced is called the reproductive trade-off. What is a reproductive trade-off A reproductive trade-off refers to the compromise that organisms make between reproductive traits, such as the number and size of offspring.

Reproductive trade-offs may occur within and between organisms, as well as between traits. A trait that is beneficial in one respect may have disadvantages in another, resulting in a trade-off. Trade-offs arise because organisms must allocate their finite energy and resources to various physiological functions, such as growth, maintenance, and reproduction.

Therefore, when organisms put more resources into one physiological function, such as reproduction, fewer resources are available for others. The number of offspring produced and the average size of offspring produced is an excellent example of a reproductive trade-off.

Some species may produce a few large offspring, while others may produce many small offspring. These strategies, however, come with different costs and benefits.
