How can the dark fur of one mouse spread to a whole population?

Biology
1 answer:
kirill [66]3 years ago
3 0
Through reproduction. dark fur is a dominant trait and eventually if offspring of the one dark furred mouse reproduce enough, it will eventually spread to the whole population because it is a dominant gene and will overpower recessive genes of the other parent organism that the dominant mouse is reproducing with.

A portion of a field has drained more rapidly than the rest, leading to drought conditions in that area several days before the
Andrew [12]

Answer:

Due to sloppy nature of the field.

Explanation:

This problem of rapidly drainage can be solved if the field should leveled because the portion is rapidly drained due to sloppy nature of the field. Sloppy nature of land moves water at the faster rate from higher elevation to lower elevation. We can see in tillage practices, the farmers used levelers in order to level the field in order to provide even resources such as fertilizers and water. So we can say that this problem can be solved if the field will be leveled.

Drag each label to the correct location on the diagram.
algol13

Diagram found elsewhere attached

Answer:

Clockwise from bottom

3. formation of mRNA in the nucleus

6. secretion of hormone  by tissue

4. initiation of DNA  replication because  of a signal given  by the hormone

2. synthesis of protein  molecule by mRNA  and tRNA

1. secretion of protein  by the cell

5. binding of the  hormone molecule  with its receptor  of the cell

Explanation:

The tissue in the top left releases a hormone. For example, a steroid hormone such as estrogen, which can impact gene expression at the level of transcription. This hormone then travels to a different cell to carry out its function. The hormone is able to enter the cell and binds receptors which recognise it. In this case, these receptors are present in the nuclear envelope. When the hormone has bound the receptor, it initiates a signalling cascade that the cell responds to.

In this case, the effect of the signal from the hormone is to initiate DNA replication. This is a common effect of hormones such as growth factors that signal the cells to proliferate.

The initiation of the signalling can  also affect how genes are expressed. In this case, an mRNA is produced in the nucleus, which is created as a result of transcription. This mRNA molecule then moves to the cytoplasm, where it becomes translated into a polypeptide sequence at a ribosome, with the help from transfer RNAs (tRNAs).

This polypeptide forms a mature protein by progressive folding and potential modifications, and is released by the cell to perform its functions.

1.Identifying characteristics of bacteria include _____.
katen-ka-za [31]
The best and most correct answer among the choices provided by the question is the fourth choice "all of the above."


<span>Bacteria vary from species to species, thus assigning many common traits to bacteria is difficult. Bacterialspecies are typified by their diversity. There are three notable common traits of bacteria, 1) lack of membrane-bound organelles, 2) unicellular and 3) small (usually microscopic) size.</span>

Answer:

A hummingbird feeding: Mutualism

Explain Interaction: The hummingbird drinks the nectar from the flower and the hummingbird may help pollinate the flower.

I'm a bit confused by the plants on the floor one.

Plants on a Forest Floor: Competition

Explain Interaction: The plants on the forests floor compete with each other for the same resources. Both may not receive enough of those resources. Note: When I was around Middle School and High-school I was only taught mutualism, commensalism, and parasitism, so let me know if competition is not a choice your teacher gives you to choose from or wasn't taught to you

Flea bites human: Parasitism

Explain Interaction: The flea drinks the persons blood as food and the person is hurt. Flea bites can be itchy and become painful. Fleas may also also carry disease.

Clownfish in Anemone: Mutualism (although I hear some people say commensalism)

Explain Interaction: The anemone provides protection and a place to live for the clownfish. The anemone may eat bits of food left over from the clownfish.
