Answer:
Apoptosis
Explanation:
Apoptosis is a process that some cells go through when their embryo divides. It is programmed cell death. Apoptosis can help protect organisms from developing cancerous growths, or the uncontrolled growth/division of cells.
Well Cells are limited in size because the outside (the cell membrane) must transport the food and oxygen to the parts inside. As a cell gets bigger, the outside is unable to keep up with the inside, because the inside grows a faster rate than the outside.
How does our lung's architecture ensure that very little oxygen is wasted?
Answer:
Gas exchange takes place in the millions of alveoli in the lungs and the capillaries that envelop them. As shown below, inhaled oxygen moves from the alveoli to the blood in the capillaries, and carbon dioxide moves from the blood in the capillaries to the air in the alveoli.

AsUsing the word "niche” in your answer, explain why this species may have a
higher probability of becoming endangered than a species that eats ten species of plants.
In interspecies competition, two species use the same limited resource. Competition has a negative effect on both of the species (-/- interaction).
A species' niche is basically its ecological role, which is defined by the set of conditions, resources, and interactions it needs (or can make use of).
The competitive exclusion principle says that two species can't coexist if they occupy exactly the same niche (competing for identical resources).
Two species whose niches overlap may evolve by natural selection to have more distinct niches, resulting in resource partitioning.

Explanation:
Raisins are a snack that is made from dehydrated grapes. While the sugar remains in the fruit, the water is removed, giving it its characteristic wrinkled appearance. A student is curious if she could rehydrate a raisin and get a grape again. She runs an experiment where she places a raisin in distilled water, another raisin in tap water, and a third raisin in salt water. The movement of water in and out of the raisin is called
Answer:
This structure which allows these passages is called the cell membrane. Substances outside the cell can move in and out of the membrane through a process called diffusion. When the substance in question is water, the process is referred to as osmosis. ... Water can be put back into a raisin through the process of osmosis.

A girl is born with hemophilia. Her dad also has hemophilia, but her mother does not.
What genetic explanation can you provide as to why the girl
suffers from hemophilia?
answer:
So daughters get 2 X chromosomes from the mom and dad and if the dad has hemophilia the daughter would get it too and sons would not get because they get Y chromosome from their dad and hemophilia is found in the X chromosome because the X chromosome is the one that has the instructions for making the clotting factor proteins.
Explanation:
A father who has hemophilia has the gene and passes it on to his daughter because daughters get two X chromosomes, one from their mother and the other from their father. This is why daughters of men with hemophilia are called obligate carriers. Since sons only receive a Y chromosome from their father, they would not have inherited hemophilia.
Hope this make sense!
Which of the following actions will provide a negative control for the investigation?
Repeating the experiment at 25°C
Repeating the experiment at 25°C
Repeating the experiment using twice the amount of hydrogen peroxide
Repeating the experiment using twice the amount of hydrogen peroxide
Repeating the experiment using twice the amount of peroxidase
Repeating the experiment using twice the amount of peroxidase
The question is incomplete, the complete question is;
Researchers investigated the influence of environmental pH on the activity of peroxidase, an enzyme that catalyzes the conversion of hydrogen peroxide to water and oxygen gas. In an experiment, the researchers added a hydrogen peroxide solution containing guaiacol to several identical test tubes and adjusted the solution in each test tube to a different pH. The researchers included the guaiacol because it caused the solutions to change color as the reactions proceeded, which the researchers relied on for measuring reaction rates. Finally, the researchers added the same amount of peroxidase to each test tube and measured the rate of each reaction at 23°C. The results of the experiment are represented in Figure 1.
Figure 1. The effect of pH on peroxidase activity
Which of the following actions will provide a negative control for the investigation?
A
Repeating the experiment at 25°C
B
Repeating the experiment using twice the amount of hydrogen peroxide
C
Repeating the experiment using twice the amount of peroxidase
D
Repeating the experiment using heat-denatured peroxidase
Answer:
D
Repeating the experiment using heat-denatured peroxidase
Explanation:
A Negative control is a situation in which a particular reagent added to an experimental set up just as all the other samples is not expected to effect any change in the responding variable.
In this case the independent variable is the pH of the solution while the responding variable is the activity of peroxidase enzyme.
A denatured enzyme is not expected to have any effect on the responding variable. Hence, this is a negative control.
The action that will give a negative control for the investigation is D. Repeating the experiment using heated-denatured peroxide.
A negative control simply means the situation where a reagent that is added to an experimental set up is not expected to have an impact on the responding variable.
It should be noted that repeating the experiment at 25°C will not lead to a negative control for the investigation. On the other hand, the repetition of the experiment using heated-denatured peroxide will lead to a negative control as the responding variable isn't affected.

Answer:
Neutron
Explanation:
Neutrons are uncharged particles found within all atomic nuclei.
An element with 5 protons, 6 neutrons, and 8 electrons has an atomic number of Group of answer choices
The mass number of an element is the sum of the protons and neutrons. The number of neutrons for a given element is the only number that can change and still have the identity of the element stay the same, (because the atomic number is the number of protons). In this case the mass number would be 11

A magazine published an article stating that drinking water obtained from waste water is harmful for health. Why is this information most likely to be incorrect? The article does not provide a scientific basis for the information magazines do not generally publish reliable scientific information drinking water has been obtained from recycled waste water since many years scientific tests show that drinking water obtained from waste water is pure and safe
Answer:
The correct answer is - the article does not provide a scientific basis for the information
Explanation:
Generally, Magazines publish articles with reliable information and sources that are universally accepted or have a scientific basis behind the information. It is already known that wastewater is recycled and purified before making it available for drinking.
In this article, there is no scientific basis behind the information as no scientific data mentioned or ignore test and practice in use from the years which is scientifically tested.

What are autotrophs and heterotrophs?An autotroph can be referred to as an organism which uses the energy from the Sun or inorganic substances present in the environment to make its own food. These organisms are also called as producers. These organisms produce their own food through the process of photosynthesis.
Heterotrophs are the organisms which takes in or which consumes other organisms for receiving energy or as the food source. These organisms are also called as consumers. Consumers are further divided into different types on the basis of their food such as carnivores, omnivores, etc.

Answer:
By one week after conception, the multiplying cells have divided into outer cells enclosing a mass of inner cells. The inner cells will become the embryo.
Explanation:
By week one, the outer cells will give the trophoblast, which will later become the placenta, while the inner cells will form the embryoblast, which will become the embryo. Then the inner cells will be in one end, and in the other one, there would be the blastocele, which is a space with fluids. This process takes place in the fallopian tube and is part of the segmentation process.
