Answer:

The cyclist’s displacement is +5 m.

Explanation:

We have, A cyclist starts at a position of origin. He takes 3 s to move east to a position of +8 m. He then cycles west to a position of +5 m which takes an additional 2 s.

It is required to find the cyclist’s displacement. Displacement of an object is the shortest path covered by it or it is given by the difference of final to the initial position.

Finally, he cycles west to a position of +5 m. Distance between final and initial position is +5 m.

Hence, the cyclist’s displacement is +5 m.

A diploid cell has two pairs of homologous chromosomes. How many different combinations of chromosomes could there be in the gam

UNO [17]

<h3>Answer;</h3>

There will be 4 different combination of chromosomes

<h3>Explanation;</h3>

A diploid cell is a cell that contains two sets of each chromosomes; thus a diploid cell with two pairs of homologous chromosomes has four chromosomes.
Gametes are produced through meiosis which is the type of cell division in which a parent cells divides into four daughter cells each with half the number of chromosomes as the parent, that is the cell are haploid.
Therefore, a diploid cell with two pair of homologous chromosomes will produce four haploid cells after meiosis each with two chromosomes.

The NET reproduction per individual per unit time (r) is _____ per mouse per month in a population of 1,000 mice where 500 mice

Phantasy [73]

Answer:

0.1

Explanation:

The Net Reproduction per individual per unit time (r) can be calculated as (births-deaths)/population size

Given that:

Population size of mice = 1,000; Birth = 500; Death = 400,

Net reproduction rate (r) = (births-deaths)/population size

r = (500 – 400)/1000

r = 100/1000

r = 0.1

The Net reproduction per individual per unit time (r) is 0.1

At the start of a 100-yard dash (race), your body relies on which reserve as its energy source?.

Rama09 [41]

The human body reserves creatinine phosphate as the energy source at the start of 100 yard dash (race).

The creatinine phosphate is converted into ATP, which is the energy package of our body. ATP is body's usable form of energy. Energy is stored in various forms in our body such as fats, carbohydrates and proteins. At a microscopic level, it is stored in molecules like creatinine phosphate. Carbohydrate and fats are the primary source of our body followed by proteins.

Our body uses three different forms of metabolism to convert these molecules in ATPs. These three processes are Phosphagen System, Aerobic Respiration and Glycolic/Anaerobic respiration.

If you know that a population is 75% the dominant phenotype and 25% is the recessive phenotype, can you determine approximately

Andreyy89

If dominant allele = p, and recessive allele = q,
and p+q = 1, then:
${(p + q)}^{2} = {p}^{2} + 2pq + {q}^{2} \\ where \: {p}^{2} \: is \: homozygous \: domin \\ {q}^{2} \: is \: homozygous \: recessive \\ and \: 2pq = heterozygous$
So if 75% have the p, then p^2 = homozygous dominant
${p}^{2} = {(.75)}^{2} = .5625$
And if the other 25% have the q, the q^2 = homozygous recessive
${q}^{2} = {(.25)}^{2} = .0625$
Now those remaining MUST be the heterozygous, thus 2pq are those:
2pq = 2(.75)(.25) = .375

Therefore homozygous dominant are 56.3% and heterozygous are 37.5%
