The plant coleus has three distinct leaf color phenotypes: green, white, and variegated (white and green mixed) the crosses are made as follows: female variegated leaves × male green leaves gives offspring with all variegated leaves female green leaves × male with white leaves gives offspring with all green leaves female with white leaves × male with variegated leaves gives offspring with all white leaves This is an example of ________.

Answers

Answer:

Cytoplasmic inheritance

Explanation:

female variegated leaves × male green leaves ⇒ all variegated leaves female green leaves × male with white leaves ⇒ all green leaves female with white leaves × male with variegated leaves ⇒ all white leaves

From these crosses, we can notice that only the female´s phenotype is expressed in the progeny, independently of the male´s phenotype. Whenever this occurs, it is probably due to the action of cytoplasmic inheritance.

Extrachromosomal or cytoplasmic inheritance refers to hereditability transmission controlled by cytoplasmic genes.

This form of inheritance lays in genes that are out of the nucleus. Even though most of the DNI is located in the nucleus, information for some characters is placed in organelles in the cytoplasm, such as mitochondria and chloroplasts. These organelles have a well-defined portion of the total cellular genome.

When a female expresses a trait that is defined by genes in the organelles, the whole progeny expresses the same trait as the female.

Mitochondrial inheritance is mostly maternal, but recent studies have demonstrated that it might also be paternal.  

 

The described experiment is an example of Cytoplasmic inheritance.

What do you mean by Phenotypes?

Phenotypes may be defined as the appearance or manifestation of a character. Phenotypes are also known as traits.

Cytoplasmic inheritance reveals the phenotypes of offspring according to female parents. In this mode of inheritance, characters or traits are stored in the organelles like chloroplast, and mitochondria, as well as in the cytoplasm.

Therefore, the described experiment is an example of Cytoplasmic inheritance.

David Tilman's study of two diatom species, each with differing abilities to utilize different levels of multiple resources, showed that coexistence is only possible when both resource levels are high. coexistence is only possible when both resource levels are low. coexistence is not possible. coexistence is possible if each species is more efficient at using a different resource than the other species.

Answers

Answer:

coexistence is possible if each species is more efficient at using a different resource than the other species.

Explanation:

Competition is an ecological and evolutive process very common in nature. Competition might be intra- or interspecific. Competition between different species in a community or ecosystem might be due to the same resource use, or the same territory, shelter, etcetera. When a resource is useful for two or more species, and limited, they compete to gain it.

The principle of competitive exclusion states that different species with the same requirements sharing the niche can not coexist indefinitely based on the same limited resource. When two competing species coexist, this is because of niche partitioning or niche differentiation.

Differentiation of effective niche is closely related to character displacement.

Character displacement is the result of interspecific competition, in which two or more species that live in the same habitat manage to avoid competition by developing different traits. Morphological divergence, or any adaptative trait development, fixated genetically, is the product of niche segregation. Species tend to differentiate morphologically in the presence of strong competitors. Traits divergence favors coexistence in the same place.

In the exposed example, both species have different abilities to utilize different levels of multiple resources. If both species live in the same place, this ability is significant to avoid competition and competitive exclusion.  

Leaf is modified into thorn where water availability is low.....give reason?

Answers

Answer:

To help conserve water or prevent loss via transpiration from the leaves

Explanation:

Some plants are found growing in habitats with little or no moisture content as annual rainfall is very low. These plants are called xerophytic plants. However, despite the low water condition, these plants are adapted to the environment and still survive.

One of their adaptation (structural) is that their leaves are reduced to thorns. Ideally, plants tend to lose water via the stomata on the leaves in a process called TRANSPIRATION. Hence, the leaves of plants adapted to a xerophytic habitat is modified to thorns in order to prevent water loss from the leaves and conserve the water.

Write a supported hypothesis of how the body would react if the peripheral nervous system was shut down while the central nervous system continues to function.

Answers

Explanation:

The real magnitude of this challenge can perhaps be best judged by considering the structural and functional complexity of the human brain and the bewildering complexity of human behavior. The human brain is thought to be composed of about a hundred billion (1011) nerve cells and about 10 to 50 times that number of supporting elements or glial cells. Some nerve cells have relatively few connections with other neurons or with such effector organs as muscles or glands, but the great majority receive connections from thousands of other cells and may themselves connect with several hundred other neurons. This means that at a fairly conservative estimate the total number of functional connections (known as synapses) within the human brain is on the order of a hundred trillion (1014). But what is most important is that these connections are not random or indiscriminate:

They constitute the essential "wiring" of the nervous system on which the extraordinarily precise functioning of the brain depends. We owe to the great neuroanatomists of the last century, and especially to Ramón y Cajal, the brilliant insight that cells with basically similar properties are able to produce very different actions because they are connected to each other and to the sensory receptors and effector organs of the body in different ways. One major objective of modern neuroscience is therefore to unravel the patterns of connections within the nervous system—in a word, to map the brain.

The pie chart indicates that deforestation in the Amazon rainforest is mostly driven by food production. The loss of large carbon-storing trees combined with the presence of methane-producing cattle is likely to intensify greenhouse gases in the Amazon.

What is deforestation in the Amazon rainforest?

Deforestation in the Amazon rainforest has significant environmental consequences. Trees store large amounts of carbon dioxide, and their removal contributes to increased greenhouse gas emissions, which are a major cause of climate change. Additionally, the cattle that are raised on cleared land produce methane, which is another potent greenhouse gas. As more trees are cleared to make way for agriculture and cattle farming, the carbon storage capacity of the forest is reduced, and more methane is released into the atmosphere.

Hence, the pie chart indicates that deforestation in the Amazon rainforest is mostly driven by food production. The loss of large carbon-storing trees combined with the presence of methane-producing cattle is likely to intensify greenhouse gases in the Amazon.

A. GUA-CAU-ACC (THIS IS WRONG)

B. GTA-CAT-ACC

C. CAT-GTA-TGG

D. CAU-GUA-UGG


Please explain, I'm very confused about this topic and I want to learn about it. No false answers or you will immediately be reported. Thanks in advance!

Answers

Answer:

A

Explanation:

The correct answer would be option A - GUA-CAU-ACC

Looking at the table of codons, for the amino acid Val, the first base (which is on the 1st column in the 6th row) is G while the second base (2nd column, 2nd row) is U. The third column can be any of U, C, A, or G (6th column, 4th row). Hence, GUA is plausible

For the amino acid His, the first base is C (1st column, 2nd row), the second is A (4th column, 4th row) while the last could be any of the 4 bases. Hence, CAU is plausible.

For the amino acid Thr, the first base is A (first column, 5th row), the second is C (3rd column, 2nd row) while the 3rth could be any of the 4 nucleotide bases. Hence, ACC is plausible.

Therefore, the correct sequence of nucleotides for Val-His_Thr would be GUA-CAU-ACC
