A breastfeeding mother requires at least __________ liters of water per day, and should drink at least one cup of water each time she breast-feeds her child.

Answers

Answer 1
Answer: The answer is two.

About 90 percent of mother's milk is water. A baby drinks up to one liter of milk per day. The simple math says it is important for a mother to take almost one liter of water for the milk and one more for her body to be hydrated. This is 2 liters per day in total. Of course, the more is the better, so drinking up to 3 liters will help the mother to stay hydrated.

Answers

The student planned to conduct an experiment to determine how a change in the pH of water affects the population growth rate of algae.To ensure that her experimental data are valid, she should use the same species of algae in all trials.
To ensure that her experimental data is valid she should check every pH with a sample of algae. She should also write down all the data collected such as what happens when the pH changes and how much algea has grown at an specific pH. In addition, she should collect data multiple times to ensure that the replication of the experiment will result in the same data being obtained.

The study of animals' structures, behaviors, functions, and evolution is called _____. ethology zoology biology physiology

Answers

Answer:

The correct answer is option B, Zoology

Explanation:

Let’s look at the definition of each term one by one –

a) Ethology – Ethology deals with the study of animal behaviour and the evolutionary factor that led to the development of such behaviour in any organism.  

b) Zoology – It is the study of animals and their nature, physiology, genetic history, evolutionary pattern and behaviour.  

c) Biology – It deals with the study of all sorts of living organisms.  

d) Physiology – It deals with the physical functioning of the organism and their parts.  

It is the zoology that includes study of every thing about animals i.e anatomy, behavior, physiology, evolutionary pattern etc. Thus option B is correct.

the answer is zoology because zoology is the study of animals and thier behaviors, envrionments, and etc.

Why is pollution never a strictly local problem

Answers

Because there are many types of pollution. 
Air pollution, water pollution, etc.
The reason it is never local is because it's a chain reaction to the environment.
Example 1:
China has the worst air pollution in the world from factories and cars. The smoke has a depleting effect on the O-zone layer which protects humans from the sun's harmful UV rays. Also, without the protection of the o-zone layer, global warming is increased (yes, it's real) and glaciers begin to melt raising water levels and so forth. So even though the smoke is all the way in China, it affects all of us living on earth.
Example 2:
Let's say there is a oil spill in the ocean which potentially kills or endangers many organisms, like fish. Even though the oil spill was only in that part of the ocean, it affects all the animals because of something called the food chain. If all of a certain fish or animal dies out and that was another animals primary source of food, then it messes up the chain.

How much sperm does it take to make a baby?

Answers

it just takes one sperm cell to go into the female egg to then produce a baby
Actually, only one sperm gets fertilised and develops into a baby. But a lot more sperms are required to carry out reproduction. This is because it is not sure if one sperm definitely gets fertilised. Some weaker sperms perish. The strongest sperm among the numerous sperms get fertilised while the others perish.

The burrowing owl is found in dry, open areas such as grasslands, prairies, savannas, deserts, farmlands, golf courses, and other urban areas throughout most of western United States and Florida, Central America, and most of South America. It makes its home in burrows of other animals and primarily eats insects and small rodents. As humans build more cities, nearby burrowing owl habitats change due to destruction of burrows and loss of prey. Which is the least likely outcome of the habitat changes that are described?AThe niche of the burrowing owl may change as it adapts to the changes.
BThe niche of the burrowing owl may change as it moves to a new habitat.
CThe population of the burrowing owl may be reduced or even become extinct.
DThe population of the burrowing owl may increase in its new surroundings.

Answers

The correct answer to the question that is being presented above would be letter D. The population of the burrowing owl may increase in its new surroundings. This is the answer because all the other choices are the most likely to happen compared to this sentence.

Which best describes the lytic and lysogenic cycles?Unlike the lytic cycle, the lysogenic cycle involves production of virus particles.
Unlike the lysogenic cycle, the lytic cycle involves destruction of the host.
Symptoms of infection appear in the lysogenic cycle but not in the lytic cycle.
For virulent viruses, the lysogenic cycle is the main way of replicating.

Answers

Answer: Unlike the lysogenic cycle, the lytic cycle involves destruction of the host

Lysogenic cycle is a method by which virus can replicate its DNA using the host cell mechanism. During this phase bacteria integrate its DNA in to host cell to make viral copy to infect the organism.

The lytic cycle is another way of the viral replicaton, it results in the destruction of infected cell and its membrane. In this cycle bacteria make viral DNA and viral protein and break and allow the newly produced virus to leave and now integrated to new cells to spread infection to other cell.


The answer is: Unlike the lysogenic cycle, the lytic cycle involves destruction of the host.

In the lysogenic cycle a virus does not kill the host. Regarding the other statements, in the lytic cycle symptoms of infection appear, and, also, it is the main way of replicating virulent viruses.
