similar in form. Which of the following hypotheses is supported by this
evidence?

Answer: Wind blows pollen from one population of plants to another, and cross-fertilization occurs. brainliest?

Explanation:

The best example of gene flow is Wind blows pollen from one population of plants to another and cross-fertilization occurs.

A pollinator is anything that helps carry pollen from the male part of the flower (stamen) to the female part of the same or another flower (stigma).

Self-pollination is the transfer of pollen from the anther to the stigma of the same flower.

Cross-pollination is the transfer of pollen from the anther of one flower to the stigma of another flower on a different.

Thus, option A is correct, as pollination leads to fertilization which involves the gamete's interaction.

Answer:

d. selective breeding

Explanation:

Answer:

The correct answer is - B) effective pumping of the ventricles ceases because the myocardial cells fail to work as a team, and the brain cannot get adequate oxygen.

Explanation:

When the heart is in an irregular and rapid heart rate due to chaotic electrical signals in the atrial chambers of the heart which leads to a very fast heart rhythm that shows 100 to 175 heart rate. That leads to failure of the myocardial cells that stop the pumping of the ventricles effectively and therefore blood would not reach the brain and the brain would not get an adequate amount of oxygen. This will result in organisms experiencing faint, blackout or stroke-like complications.

Answer:

Structures that have no apparent function and appear to be residual parts from a past ancestor are called vestigial structures. Examples of vestigial structures include the human appendix, the pelvic bone of a snake, and the wings of flightless birds.

Answer:

hello your question lacks the required options hence I will give you a  general answer

answer :  gg ( gray fly )  * Gg ( heterozygous black fly )

Explanation:

Let black body ( G ) be the dominant allele to gray body ( g )

hence the possible combination that will represent a parental cross when a gray fly is crossed with a heterozygous Black fly will be

gg ( gray fly )  * Gg ( heterozygous black fly )

Hello!!

Heterogeneous would be the answer here. The definition of heterogeneous is: composed of dissimilar parts which can be separated easily and which are unevenly distributed in the mixture. So, heterogeneous would be a mixture where the composition is varied.

Answer: it makes up the cell or it’s the to-do of the cell kinda like coding

Explanation:

Answer:

Mendel's law of dominance states that in a heterozygote, one trait will conceal the presence of another trait for the same characteristic. Rather than both alleles contributing to a phenotype, the dominant allele will be expressed exclusively.

Option C

GOOD LUCK FOR THE FUTURE! :)

Planting of trees is not a factor contributing to the loss of biodiversity. Thus, option C is correct.

The main purpose of the classification of the Five kingdom has been known R.H. Whittaker.  The five kindoms that has were included in this proposal were the Fungi, Protista, Monera.

Animalia as well as the kingdom Plantae. There are mainly five criteria or the conditions based on which the classification has been madeup of. These criteria has been includes the structure of the cell,  as well as the nutrition mode, organisation of the thallus, or the relations of reproduction and phylogenetic.

Based on shoe characteristics they were to develop a classification hierarchy of shoes, beginning with the shoe "kingdom" and becoming more and more specific, just like scientists did for the classification of living things.

Therefore, Planting of trees is not a factor contributing to the loss of biodiversity. Thus, option C is correct.

Question:

Use the following dichotomous key to identify an irregular blue flower with five petals and a fruit that is a ripened flower ovary or follicle.

Dichotomous Key of Ranunculaceae

#1.

a. Fruit is a group of alkenes.............................. go to step 2

b. Fruit is a group of follicles..............................go to step 4

#2.

a. Petals are not present.....................................go to step 3

b. Petals are present............................................Ranunculus

#3.

a. The flower has 4 sepals.................................. Clematis

b. The flower has 5 sepals................................... Anemone

#4.

a. The flowers are regular..................................... Aquilegia

b. The flowers are irregular................................... Delphinium

The flower is a: A. Anemone B. Clematis C. Delphinium D. Ranunculus

Answer:

The species belongs to Delphinium genera.

Explanation:

A dichotomous key is relatively simple to interpret. All you need to do is to:

- carefully observe your organism,

- know some technical terms or have a biological dictionary, and

- follow the descriptions.

The dichotomous key is going to lead you to the answer.

In the example, we have a plant species with irregular blue flowers and five petals. The fruits are a ripened flower ovary or follicles.

So, let us begin, step by step. For each number, we are going to have two options (a and b). By knowing our organism, we need to decide which one is correct and follow indications.

#1.

a. Fruit is a group of alkenes.............................. go to step 2.

b. Fruit is a group of follicles..............................go to step 4.

We know that our fruit is a follicle. Option a is not correct (it is not a group of alkenes). Option b is the correct one. Knowing this, we must go to step four. ***Note: In the hypothetical case that the fruits were a group of alkenes, and option a was correct, we should go to step two, as indicated***.

#4.

a. The flowers are regular..................................... Aquilegia

b. The flowers are irregular................................... Delphinium  

We know that our flower is an irregular one. So the correct option is b. This option leads us to Delphinium genera. Our species belongs to this taxonomic group. ***Note: In the hypothetical case that the fruit was actually a regular flower, and option a was correct, our species would belong to Aquilegia genera***

Answer:

It may be that synthesis in population dynamics has been slow to emerge because population change is more complicated than it first appears. After all, population change is determined ultimately by only four factors: birth, death, immigration, and emigration.

Explanation:

Research has shown that population size and growth are important factors in the emission of greenhouse gases. ... While population-driven emissions from developed nations are estimated to contribute 42 percent of CO2 emissions between 1985 and 2020, they are expected to contribute only 3 percent between 2025 and 2100.

If sewage is only partially treated before it is disposed of, it can contaminate water and harm huge amounts of wildlife. Alternatively, leaking or flooding can cause completely untreated sewage to enter rivers and other water sources, causing them to become polluted. The consequences aren't great

Factors influencing population growth

+Education. ...

+Quality of children. ...

+Welfare payments/State pensions. ...

+Social and cultural factors. ...

+Availability of family planning. ...

+Female labour market participation. ...

+Death rates – Level of medical provision.

Answer:

5.0 x 10-4 g/kg

Explanation:

This is because

I mrad is equivalent to 1/100,000j/kg

Therefore,

To convert 50 mrad to j/kg

= 50/100,000

= 5 × 10^-4j/kg.

Millirad is a decimal unit or rad which is the unit for measuring absorbed ionization radiation.
