Answer:
Green plants and trees use photosynthesis to make food from sunlight, carbon dioxide and water in the atmosphere: It is their primary source of energy. The importance of photosynthesis in our life is the oxygen it produces. Without photosynthesis there would be little to no oxygen on the planet.
Explanation:
Answer:
E. 1/600
Explanation:
Hint:
The probability of fixation of a new neutral mutation is 1/(2N)
Given N as 300
= 1/(2×300)
=1/600
Therefore,
1/600 gives a sure fixation of one allele from the large population
The correct term to fill in the blank would be intensity. The intensity of exercise determines whether carbohydrates or fat is the predominant source of energy production. During high-intensity workouts, it is the fat that is used as the source of energy production while low-intensity exercises would only use the carbohydrates present for energy.
In this question, the ant has 4 pairs of chromosomes. Each pair of chromosomes will be separated in a gamete, resulting 4 unpaired chromosomes. That is why gamete is called haploid or n.
That means only 1 of the 2 chromosomes that will be carried into a gamete, assuming the gene heterozygote then there would be 2 possibilities. Since each chromosome pairs can produce 2 possibilities for each male or female, their interaction will result as (2x2) 4 possibilities.
Then for 4 chromosomes would be 4^4 possibilities= 256 possibilities of offspring
<h3><u>Answer</u>;</h3>
Key
A sorting device that is useful in classifying by observation is a <u>key</u>.
<h3><u>Explanation</u>;</h3>
- <em><u>Classification key or taxonomic key is a device that is used by scientists to identify unknown organisms. </u></em>
- They are constructed so that the user gets a series of choices about the characteristics of the unknown organisms.Thus, by making the correct choice at each step, one is led to the identity of the specimen.
- Therefore<u><em>, keys can be used to identify a living organism or determine which group it belongs to</em></u> by answering questions on the key about characteristics of living things.
