Are birds and crocodiles homologous or analogus behaviors?

Biology
1 answer:
Nady [450]3 years ago
4 0

Analogies are the result of convergent evolution. Interestingly, though bird and bat wings are analogous as wings, as forelimbs they are homologous. Birds and bats did not inherit wings from a common ancestor with wings, but they did inherit forelimbs from a common ancestor with forelimbs.

Predict the type of progeny produced by Mendel's crosses between pure-breeding plants with discrete, antagonistic traits, such a
asambeis [7]

Answer:

The progeny produced is 100% heterozygous individuals.

Explanation:

Remember that in Mendel crosses, there are two alleles for each character, in this case for the color of the flowers.

When the problem refers to pure varieties, it refers to individuals with two equal alleles for the same gene.

If two pure varieties with antagonistic characters intersect, 100% of heterozygous individuals will be obtained in the offspring.

As for its phenotype, it will depend on which allele is dominant over the other.

Mendel bred an unknown plant displaying a dominant phenotype with an individual showing the recessive phenotype; then, he analyz
kodGreya [7K]

What Mendel did according to the illustration would be called test-crossing.

<h3>Test-crossing</h3>

In genetics, test crossing is a procedure through which the zygosity of an individual can be determined - whether it is homzygous or heterozygous.

Test crossing requires that an organism who displays a dominant trait but whose zygosity is unknown is crossed with another organism of the same species but who displays the recessive version of the same trait.

By so doing and using the knowledge of probability, the resulting offspring from the cross will be used to determine the zygosity level of the parent.

The Water Cycle What would most likely happen if it didn’t rain in a certain area for a long period of time?
Mariana [72]

Answer:

The air is full of water, as water vapor, even if you can't see it. Condensation is the process of water vapor turning back into liquid water, with the best example being those big, fluffy clouds floating over your head. And when the water droplets in clouds combine, they become heavy enough to form raindrops to rain down onto your head.

What is a positive and negative impact?<br><br> (Giving brainliest)
12345 [234]

Answer:

Positive affect" refers to one’s propensity to experience positive emotions and interact with others and with life’s challenges in a positive way. Conversely, "negative affect" involves experiencing the world in a more negative way, feeling negative emotions and more negativity in relationships and surroundings.

These two states are independent of one another, though related; someone can be high in positive and negative affect, high in just one, or low in both. Both states affect our lives in many ways, particularly when it comes to stress and how we handle it.
