Why element of the xylem in vascular bundle is less than the phloem?

Answers

Answer 1

Answer:

The element of the xylem in vascular bundle is less than the phloem because the Xylem carries water which is a raw material to manufacture the food.

Explanation:

A pair of xylem and phloem is termed to be a 'vascular bundle'.

The purpose of the Xylem tissue is to transport the water from the roots to the stems and leaves. Other compounds are also transported which are dissolved in the water. Phloem, on the other hand, helps in transporting food from leaves to other parts of the plant.

Anya and Greg are working in their research laboratory. Anya tells Greg that one of the mice has a 50% probability of having the alleles DD and a 50% probability of having the alleles Dd. How can Anya explain her reasoning? In two out of 50 times, the mouse has the alleles DD or Dd. The probability that the mouse has the alleles DD is equal to the probability that it has the alleles Dd. The mouse is twice as likely to have the alleles DD than it is to have the alleles Dd. There are two more possible outcomes besides the mouse having DD or Dd alleles.

Answers

Answer:

Option B: The probability that the mouse has the alleles DD is equal to the probability that it has the alleles Dd.

Explanation:

Anya tells Greg that one of the mice has a 50% probability of having the alleles DD and a 50% probability of having the alleles Dd.

She can explain her reasoning by saying that both pairs of alleles (DD and Dd) has equal chance of being expressed i e, the probability that the mouse has the alleles DD is equal to the probability that it has the alleles Dd. Both pairs each has 0.5 chance of occuring.

Answer:

Explanation:

A Dominant Allele is an Allele that express itself.

DD- this represent a dominant homozygous allele

Dd- represent a dominant heterozygous allele

When an individual with DD is crossed with Dd we will have DD,Dd,DD,Dd

Phenotypic ratio is 2:2

i.e homozgous dominant crosses with heterozygous dominant

which means both DD and Dd have 50% chance of occuring in the genotype and the probabality is the same.

Note that in the phenotype of an individual with homozygous dominant (DD) is the same phenotype with heterozygous dominant(Dd)

What are the five main functions of nematodes in soil?

Answers

Answer:

Nematodes are the bacterial feeders, fungal-feeders, plant parasites, predators, and omnivores.

Explanation:

hope this helps :)

Answer:

Nematodes play an important role in nutrient cycling. In particular, they play a key role in the nitrogen cycle. Nematodes take in nitrogen and excrete it in a form that plants and bacteria can use.

Nematodes graze on bacteria, plants, and other soil organisms. In ecosystems, nematodes play a major role in regulating the populations of their prey organisms.

Nematodes carry fungi and bacteria in and on their bodies. As nematodes move through the ecosystem, they disperse the bacteria and fungi.

Nematodes are a part of food chains and food webs. They are an important food source in many ecosystems.

Nematodes impact the health of other organisms. Some help prevent, or suppress, disease by eating other disease-causing organisms. Other nematodes cause disease in plants and animals.

Explanation:

You prepare an agar plate by spread plating & place an antibiotic disk in the middle of the plate. After incubating for a day at 37 degrees C, there are no bacteria on the plate. Which of the following is NOT a reasonable interpretation of what might have happened?
O The bacteria in the culture tube were already dead when you made the plate
O The medium used was defective and provided no nutrition for the bacteria
O The bacteria grew all over the plate but were then killed by the antibiotic
O The spreading tool was too hot when spreading the bacteria

Answers

Answer:

A.The bacteria in the culture tube were already dead when you made the plate

Explanation:

Antibiotics are the chemical substance used to kill or stop the growth of bacteria and some other microorganism.

Antibiotics are added to agar plate during experiment for the selection of only those bacteria with resistance to that antibiotic.

There can be several interpretation for the absence of bacteria such as:

The bacteria grows on the nutrients in the medium but due to defective medium they were unable to grow and die.It may also happen bacteria might have grown in all over the plate but due to the action of antibiotic, all the bacteria got killed.Tool used for spreading might kill bacteria as it was hot and bacteria may not be able to tolerate the excessive heat and die.

Hence, the only not reasonable interpretation is bacteria in the culture tube were already dead when you made the plate.

So, the correct option is A.

Answer:

Animals release carbon dioxide when they breathe which plants take in to help make food

Animals release carbon dioxide when they breathe which plants take in to help make food. So the correct option is D.

Why do animals and plants depend on each other?

All species present on earth depend on each other for performing basic life processes. Humans are not able to survive beyond a particular range of temperature and pressure. For all the species to survive, a healthy environment is required.

Plants and animals are dependent on each other. This is because, in ecological systems, no species can survive alone. Animals are dependent on plants. Plants are the primary producers in our ecosystem. They produce food that is consumed by primary consumers and the primary consumers are consumed by secondary consumers.

Plants use carbon dioxide for photosynthesis and it results in the production of oxygen. This is used by animals for the process of respiration.

Plants depend on animals for several reasons. These can be fruit and seed dispersal, pollination, and also for the carbon dioxide that the animals produce. Thus, both plants and animals are interdependent on each other.

Therefore, the correct option is D.

They are not on the same chromosome because when genes are located on different chromosomes they segregate independently.

How do you know if genes are on the same chromosome?

We say that a gene is in linkage or gene linkage when it is on the same chromosome and does not segregate independently at the time of the formation of a gamete. We know that chromosomes are formed by a large sequence of genes that is responsible for determining the characteristics of a species.

Whit this information, we can conclude that they are not on the same chromosome because when genes are located on different chromosomes they segregate independently.

Explanation:

So far, we have primarily discussed human adaptations independently of one another. In real life, of course, each person has numerous coexisting ancestral adaptations. Ignore what you know of your family history and consider only your physical traits for the following adaptations: skin color, lactose tolerance, and body shape. Based on these three traits, in what part of the world might your ancestors have originated? Do all three of your traits suggest similar ancestry? Be sure to explain your hypothesized determination using evidence related to all three traits, and be sure to think about all the forces of evolution that might impact your unique history (such as gene flow and founder effect).

Answers

Answer:

about skin coloration:

Regarding these modifications, we can say that it influences not only the knowledge of evolution but also on the development of strategies for the management of many diseases, so we know that these changes are not produced by a single agent and factors such as Melanin, a substance produced by melanocytes and which gives the tint to each tone, also includes influences such as exposure to sunlight, both in frequency and geographical area from which it is made. Keratin is also found as its own dermal factor. According to this, there has been an adaptation of the phenotype of each individual mainly to the UV environmental factor that can make changes and modify skin tone.

About lactose tolerance:

It is known that historically, after childhood for many people it was very difficult to continue consuming milk, because the enzyme lactase was not found in them and lactose digestion became very difficult, nowadays it is believed that the weather has influenced to improve digestion

About the body shape:

The inherited factors are very important, from the different habitats of our ancestors, which for reasons of hunting, solar exposure, type of food, were being inherited, today it is known that there are 3 main forms of body types including the endomorph, ectomorph and mesomorph, the main advantages depending on where the individual lives will adapt to persist in the next generation, as well as to use new ways of obtaining food can modify it
