Completely different organisms may have similar adoptions True or false

Why do traits that give an organism a disadvantage exist during meiosis? Please be as descriptive as possible and write it in yo

Roman55 [17]

Answer:

Meiosis is important because during sexual reproduction, it ensures that all produced organisms have the correct number of chromosomes. It is also responsible for producing genetic variations during the process of recombination, and it repairs some genetic defects.

The disadvantage from not having the trait normally arises only after the reproductive stage of the individual's lifecycle is mostly over. This is a special case of "no strong pressure", because evolution selects genes, not the organism. In other words the beneficial mutation does not alter the reproductive fitness.

Devise an experiment to test the hypothesis that bright orange coloration in butterflies acts as a "warning" to potential

Murrr4er [49]

Answer and Explanation:

As I don't have access to live butterflies, the control group would be clay models that do not exhibit warning coloration, e.g. beige / white / brown. In contrast, the experimental group would be the clay models that exhibir a strong warning coloration such as color orange / red.

After preparing the clay 'prey', I would locate them in specific places outside where birds are able to detect them. Moreover, I would use a webcam to monitor the recurrence of birds in the area.

1st experiment: Test whether birds approach the prey that exhibits both warning coloration (experimental group) and dull coloration (control group). Then, record the minutes they spent wandering near the prey.

2nd experiment: Test wheter birds feed on the prey that exhibits both warning coloration (experimental group) and dull coloration (control group). Record time.

Carry out statistical analyses.

Present results and discuss.

What is the principle for dating materials using radioactive isotopes

nevsk [136]

It is based on a comparison between the observed abundance of a naturally occurring radioactive isotope and its decay products, using known decay rates.

<h3>How are isotopes used in radioactive dating?</h3>

These isotopes decay within the rocks according to their half-life rates, and by choosing the fit minerals and measuring the relative amounts of parent and daughter isotopes in them, the date at which the rock crystallized can be determined.

Thus, It is based on a comparison between the observed abundance of a naturally occurring radioactive isotope.

What do you think would happen if there was more glucose (sugar) than available NAD+? Explain.

EleoNora [17]

Answer:

n people who have developed diabetes, glucose builds up in the blood, resulting in hyperglycemia. ... And, too much sugar in the bloodstream can cause other types of damage to body tissues, which can increase the risk of heart disease and stroke, kidney disease, vision problems, and nerve problems in people with diabetes.

What are the classification levels of humans for order, suborder, family, tribe, genus, and species? Group of answer choices Mam

Finger [1]

Answer: Human classification levels for order, suborder, family, tribe, genus and species are;

Primates, Primates, Haplorhini, Hominidae, Hominini, Homo, and sapiens , Hominidae, Hominini, Homo, and sapiens

Explanation:

Human taxonomy is the systematic classification of humans.

The order is primates include placenta animals including humans, that have good eyesight, flexible hands and feet, well developed brain and they include man, lemurs, apes e.t.c.

Suborder Haplorhini have a plate which cause a separation between the temporal fossa and eye socket.

Family Hominidae include group of animals that have well developed forearms and flattened digits nails.

Humans are called homo sapiens which means wise man. It is a Latin word...

Homo means man and sapiens means wise.
