How might the trait`s heritability affect the species` ability to undergo natural selection?

Biology
1 answer:
Paha777 [63]3 years ago
8 0

Answer: If it is almost impossible for a favorable trait to get passed down to offspring due to reproductive struggles, the species would not be able to undergo natural selection due to a lack in appearance of a trait.

Explanation:

If there are only two organisms with the adaptation, both of which lack any reproductive abilities, the odds of most of the species <em>not</em> dying out are very low. Only those two will have the adaptation and they rest will die out.

I hope I helped! :)

3. How are frog eyes different from human eyes?​
Nastasia [14]

Answer:

Most frogs see well only at a distance, but they have excellent night vision and are very sensitive to movement.This peripheral vision helps them spot predators and prey. Humans and other mammals focus images by changing the shape of the lens. Like a camera lens, frog eyes focus by moving the lens back and forth.

Answer:

There is an increase in demand for higher quality and quantity of food and other products.

Explanation:

There is an increase in demand for higher quality and quantity of food and other products. So, there is a huge requirement for technological innovation.  Investment is needed in research and development to develop crops that are pesticide-free, resistant to disease, and able to face various weather conditions.  Vertical farming and carbon-capture technology can be used to meet growing world food demands.

Classify the following organisms into their respective kingdoms (i) Yeast (ii) Penicillium (iii) Rhizobium (iv) Mushroom (v) Amo
lions [1.4K]

Answer:

(i) Yeast- Kingdom Fungi

(ii) Penicillium- Kingdom Fungi

(iii) Rhizobium- Kingdom Eubacteria

(iv) Mushroom- Kingdom Fungi

(v) Amoeba- Kingdom Protista

(vi) fish- Kingdom Animalia

Explanation:

Living organisms were classified into a large group called KINGDOM, which represent the largest and most generic grouping consisting of organisms that share a few similarities. The kingdoms that living organisms were classified into are as follows: Plantae, Animalia, Fungi, Protista, Eubacteria, Archaebacteria, etc.

Based on the question, the mentioned organisms are classified into the following kingdoms:

(I) Yeast: Yeast is a unicellular microbe classified under the Kingdom Fungi due to possession of chitin in its cell wall and other similar features with members of kingdom Fungi.

ii) Penicillium- Penicillium is a genus classified under the Kingdom Fungi.

(iii) Rhizobium- Rhizobium is a genus of prokaryotic organism (lack membrane-bound nucleus and organnelles) classified under the Kingdom Eubacteria.

(iv) Mushroom- Mushrooms are saprophytic (heterotrophic) species of organisms classified under the Kingdom Fungi.

(v) Amoeba- Amoeba is a genus of unicellular eukaryotes classified under the Kingdom Protista.

(vi) fish- Fishes are organisms classified under the Kingdom Animalia

2. Describe the problem that McClintock suggested Harriet Creighton solve.
harina [27]

Answer:

'Cross experiments done by Morgan, illustrating the X-inheritance link of a mutation Thomas Hunt Morgan moved intensely in a program of breeding and crossing miles of fruit flies at New York University in a room that was renamed the Fourth of the Flies. He tried to mutate the flies with various means (X-rays, centrifuges, etc.) .The fruit fly which has 4 pairs of chromosomes. One of those pairs was identified as containing X and Y sex chromosomes. He applied Mendelian principles in flies. Morgan's inheritance study demonstrated inheritance linked to sex, and is one of the first evidences that confirm the chromosomal theory of cross-based inheritance. In 1909, Morgan detected a fruit fly (Drosophila melanogaster) with a strange mutation which he called "white eyes", due to the coloration of his eyes (contrary to normal, which is red). Analyzing this fly under the microscope Morgan discovered that it was a male, and could use it as a stallion so that he could observe how the new characteristic of white eyes would pass from generation to generation.All the offspring of this cross will have red eyes, which He made Morgan suspect that something strange had happened, since the color of the father's eyes could not have disappeared. He decided to take a couple of "daughters flies" and cross them together, just to see what happened. Morgan's surprise was very great, observing that among the "granddaughters" flies only males had white eyes. The problem then was to explain what had happened during the hereditary transmission for the color of the white eyes only the males possessed. .
