How does meiosis most benefit a species?
It decreases the number of chromosomes.
It increases genetic variation.
It increases the number of chromosomes.
It increases mutations.
Answers
Answer:
It increases genetic variation.
Explanation:
Meiosis does not decrease the number of chromosomes nor increase the number of them, it merely splits them.
While it could increase mutations, this might not necesarily be a good thing.
However, it does increase genetic variation, especially during the process where crossing over occurs. Increased genetic variation is beneficial for the population for many reasons like higher resistance to certain diseases. Increasing genetic variation also makes a species look unique from other members of the species.
John had unattached earlobes like his father, but his mother has attached earlobes. What is johns genotype with unattached being dominant
Answers
Genotype refers to the complete genetic make-up and can also be referred to as the alleles an organism carries on a particular gene.
John's genotype with unattached being dominant is Aa.
Using A to represent the allelesSince his mother has attached earlobes, her condition can only be inherited in the recessive condition (aa). So for John to have an unattached earlobe, his father has to be either AA or Aa. Therefore John's genotype would be AaLearn more about genotype: https://brainly.com/question/22117

Question 11
1 pts
A runner expends an average of 4 kcal per minute during a two hour run. She want to eat a meal of
50% energy from carbohydrate, 25% of energy from protein and 25% of energy from fat, how
much protein would their meal have to contain, in order to replenish their expended energy?
Answers
Given what we know about nutrition, we can confirm that the runner's meal would have to contain 30 grams of protein.
The runner in question wishes to complete a two-hour run while expending 4kcal or calories per minute, for a total of 480kcal. Furthermore, the runner wishes for only 25% (120kcal) of this energy to come from a source of protein.
Since every gram of protein adds 4 calories of energy to the meal, and we have to account for 120 calories, the runner will have to consume 30 grams of protein to achieve the desired results.

Applying the systems thinking techniques, outline the practical steps that can be taken to address drought
Answers
Some practical steps to address drought may include the implementation of efficient water usage techniques, the protection of vegetation, and the use of methods to retain moisture in the soil.
What is a drought?A drought is classified as the shortage or absence of water for a prolonged period of time in a region. These can be caused by a prolonged lack of rainfall.Other factors include poor water management and lack of vegetation.Methods to avoid droughts.The planting and protection of vegetation, primarily those adapted to dry environments, is important in preventing drought.Furthermore, the correct implementation of efficient water usage techniques can aid in preventing drought by limiting the amount of water that is wasted. Lastly, the use of mulch and other water retainers can be an effective method in keeping the soil moist and aids in the previous two methods.Therefore, we can confirm that the most effective ways to avoid droughts are to practice efficient water use so as to not waste water, to plant and protect vegetation, and to use mulch and other moisture-retaining methods to keep the soil from drying.
