What is stored in the nucleus?
Answers
Answer: The nucleus (plural, nuclei) houses the cell's genetic material, or DNA, and is also the site of synthesis for ribosomes, the cellular machines that assemble proteins. Inside the nucleus, chromatin (DNA wrapped around proteins, described further below) is stored in a gel-like substance called nucleoplasm. hopes this helps pls pls pls give me brainliest.
Explanation:
Answer:
Within the nucleus, DNA molecules, the cell's genetic machinery, are stored, repaired, transcribed and eventually replicated. Around the outside of the nucleus is an envelope consisting of two layers of membrane.

Explanation:
3. You are studying a population of pangolins (a scaly anteater), and you determine that there are two scale phenotypes: a thick scale that is dominant to a thin scale. You also find that thick-scaled individuals are better able to survive encounters with predators.
What evidence would you need in order to determine if this selective advantage is changing the population? (1 point)
-The number of individuals displaying each phenotype in the current generation.
-The number of individuals displaying each phenotype in the offspring.
-The number of individuals that survive predator encounters.
-The number of individuals displaying each phenotype in both the current generation and the offspring.
Answers
Answer:
The number of individuals displaying each phenotype in both the current generation and the offspring.
Explanation:
The number of individuals displaying each phenotype in both the current generation and the offspring. The correct option is 4.
What is phenotype?The phenotype is the set of observable characteristics or traits of an organism in genetics.
The term encompasses the organism's morphology, developmental processes, biochemical and physiological properties, behaviour, and behavioural products.
To see if the thick scale phenotype's selective advantage is changing the population, we must compare the frequency of the thick scale phenotype in the current generation to its frequency in the next generation.
This would necessitate data on the number of people who exhibit each phenotype in both the current generation and their offspring.
As a result, the evidence we require to determine whether the selective advantage is changing the population is "the number of individuals displaying each phenotype in both the current generation and offspring."
Thus, the correct option is 4.

asap Waste water from nuclear power plants is generally:
cold
muddy
radioactive
warm
Answers
Answer:
Warm is the Correct Answer
Explanation: I know this because the water that is used to cool Nuclear Power plants is usually returned back into the ocean but the water is warmer than the water in the ocean. This can lead to Thermal Polution which can kill species of fish that aren't used to such warm water.
explain why fermentation wold take over and not the krebs cycle.how long would it last?
Answers
Answer:
Fermentation takes over the krebs cycle in anerobiotic conditions. The lack of oxygen prevents oxidative phosphorylation and the formation of new oxidized compounds which can only be reformed through the reduction of pyruvate to lactate: through this process glycolysis can continue to function and we can have the production of ATP. The problem is that only 2 ATPs are formed: this is not enough to sustain the life of the cell so, over a period of time that varies from cell to cell (for example the myocyte survives for 40 min, nerve cells fastly die in ischemia), it will go to death if no new oxygen arrives.
what is the endocrine system and how does it work
Answers
What Does the Endocrine System Do?
Endocrine glands release hormones into the bloodstream. This lets the hormones travel to cells in other parts of the body.
The endocrine hormones help control mood, growth and development, the way our organs work, metabolism , and reproduction.
The endocrine system regulates how much of each hormone is released. This can depend on levels of hormones already in the blood, or on levels of other substances in the blood, like calcium. Many things affect hormone levels, such as stress, infection, and changes in the balance of fluid and minerals in blood.

Explanation:
This is because the X chromosome is large and contains many more genes than the smaller Y chromosome. In a sex-linked disease, it is usually males who are affected because they have a single copy of X chromosome that carries the mutation.

2. What are three factors that affect birth and/or death rates?
Answers
Answer:
Political, economic, and religious
Explanation:
Age: Mortality rates are different in different age group. Mortality is high among children and old people but it is low among youths.
Sex/gender: Studies have shown that women have longer life expectancy than men. It may be due to biological and social causes that affectthe life expectancy. Besides, it is also found that death rate among infants is also similar to the life expectancy of adults. The death rates for male infants are higher than those of female infants.
Nutrition Levels: The children, especially under five years of age, die due to lack of nutritious foods. A balanced diet is a must for a healthy living. There are deficiency diseases caused by protein, energy, carbohydrate, malnutrition and also by micro-nutrient deficiencies. These are the causes of high death rates.
