Answer:
K-strategists
Explanation:
Reproductive pattern in organisms can be typically categorised into two:
1. K- Strategy
2. R- Strategy
K-strategists are organisms that lives in very stable environments and gives birth to fewer organisms. Most of these organisms reproduce close the carrying capacity of their habitat. They offer support and protection to their progeny to the points where they become indepedent. The mortality rate is very low in such organisms and so is the birth rate too.
R-strategists are organisms whose main aim is to populate and dominate an environment. They reproduce exponentially and offers no life support to their progeny in their early developmental stage. They often occupy unstable and highly unpredictable environments. Most R organisms have a very low and short life expectancy. Since they produce more offspring and they live under adverse environments, mortality rate is high.
Examples of K-strategists are elephants and man
Examples of R-stategists are grasses and microbes.
This is called the Green house effect
Answer:
1. genetics
2. constant
3. genetic drift
4. Modern synthesis combines the ideas surrounding evolution and natural selection with those of genetics.
5. A genotype is the genetic makeup of an organism. It describes the DNA that underlies a trait. There are dominant and recessive alleles and heterozygous and homozygous genotypes. A phenotype is the physical manifestation of that genotype.
6. The most common type of mutation is a deleterious mutation. Natural selection acts to remove this allele from the population.
7. The most common type of observed mutation is a neutral mutation. This mutation doesn't impact natural selection in any noticeable way since it doesn't impact the fit of that organism. Since neutral mutations convey no advantage, they generally must spread in a population through drift. Many also will disappear through drift.
8. During sexual reproduction, each organism is provided a copy of chromosomes from each parent, and this allows for new combinations of DNA.
9. This isn't an example of genetic drift because there's a genetic component to the ability to withstand severe temperatures. Therefore, this is an example of natural selection, related to surviving extreme environmental conditions
Explanation:
Answer:
The muscular system can be broken down into three types of muscles: skeletal, smooth and cardiac. The muscles in the body support movement, help maintain posture, and circulate blood and other substances throughout the body. ... It pumps out 2 ounces (57 grams) of blood with every heartbeat.
