Answer: Dominant: red, recessive: white.
Explanation:
Alleles are different forms or versions of a gene, and they can be described as either dominant or recessive.
Dominant traits are those that are seen in a heterozygous genotype. It means the organisms has two different alleles for a gene, one is dominant while the other one is recessive. A dominant allle dominates over the recessive alleles and it masks the effects of this recessive allele. This means, the offspring only needs to inherit one dominant allele to have a dominant trait.
In the example, a red-flowered plant is crossed with a white-flowered plant. And all plants on the next generation are red. If each plant from this offspring inherites one allele of each parent, they have one red allele and one white allele. Since they are all red, we can say red color is dominant and white color is recessive. Because red allele has a dominant phenotype.
Answer:
cells
Explanation:
cells carry out functions for life
What is the FUNCTION OF THE SETAE?
Answer:for filter feeding
Explanation:setae are used by filter feeders such as small crustaceans,baleen whales and marine prions.these organisms feed on suspended Feed in waters and so need a structure that allows them to extract the suspended particles from the water
Majorly population growth is affected by birth and death rates and also on the migration, immigration factors it also depends on the favourable condition.
like if environment is favorable enough food, living space, no competition, no lethal diseases and also temp. water availability) than growth will be good, if not than growth will be less.
These density-independent factors include food or nutrient limitation, pollutants in the environment, and climate extremes, including seasonal cycles such as monsoons. In addition, catastrophic factors can also impact population growth, such as fires and hurricanes.
Fertility Rate
The factor which affects the growth of the population in the biggest way is the fertility rate. The fertility rate is typically measured by the number of children per one woman of child-bearing age. If the fertility rate is larger than 2, the rule of thumb is that the population should rise, as there are more children than their parents. On the other hand, if this ratio is below 2, the population of the region may be destined for a decline.
Mortality Rate
A key factor affecting the growth of the population is the death, or mortality, rate. Just as the birth of new people increases the population size, deaths decrease it. The factors that affect the mortality rate include the availability and affordability of quality health care and lifestyle habits – for example, whether they smoke or do physical exercises regularly.
Immigration and Emigration
Cross-border migration is the act of people moving from one country to another. It affects the population size of both the host and destination countries. Emigration is caused by a number of factors, such as fleeing war, finding education, seeking new jobs or joining family members. When a person emigrates from a country, its population shrinks. When someone moves to a country from another place, it is known as immigration. Whether or not a person is allowed to immigrate is controlled by the country that will host this person.
