Answer:
Answer
Explanation:
B because the more the sun is titled the more heat=different season.
Because Earth is tilted on its axis, parts of Earth get more hours of sunlight during different times of Earth's yearly orbit. As Earth orbits around the Sun, its axis is tilted at an angle of about 23.5 degrees. Hence the correct option is D.
Why do the temperatures change over the months?The temperatures change over the months primarily because of Earth's axial tilt. As the Earth rotates around the sun, the angle at which sunlight hits different parts of the Earth changes.
This is because the Earth's axis is tilted about 23.5 degrees relative to its orbit around the sun. When a particular hemisphere is tilted toward the sun, it receives more direct sunlight, resulting in warmer temperatures.
Conversely, when that hemisphere is tilted away from the sun, it receives less direct sunlight, resulting in cooler temperatures. This cycle repeats itself annually, causing changes in temperatures over the months.
Hence the correct option is D.

Which best describes how to classify water?
A It is an element because it is made
from a pure substance.
В
It is a compound because it is made
of a single kind of molecule.
© It is a mixture because it is composed
of more than one molecule.
D It is a solution because it is a
homogenous mixture of different
compounds.
Answer:
D
Explanation:
Water is a compound and scientifically known as H[tex]_{2}[/tex]0 (2 hydrogen atoms and 1 oxygen). Therefore, the answer is...
Not A because water is not an element of one pure substance; rather, it is a compound and can be broken down into two pure substances.Not B because the statement contradicts itself: a compound is made of different atoms and, thus, different molecules.Not C because a mixture contains different substances that are physically -- not chemically -- combined. And as we know, water is a compound, which means that its atoms are chemically bonded to one another. Or else it would just be 2 free hydrogen atoms and 1 oxygen.D (yay!) because it is not the *most* accurate, but simply the best description of those provided. Water can be described as a homogenous (uniform in appearance) mixture because, minus the "mixture" part, that's what it is, essentially: a substance that looks pure but is really made of up different molecules.Ngl this was tricky, but I hope this helps :)

Match the following terms with the correct definition. Arterioles Arteries Capillaries Venules Veins Small vessels that carry blood away from the heart to the capillaries are __________. Muscular-walled vessels that carry blood away from the heart are _______. One-cell-thick microscopic vessels that function to exchange nutrients and wastes are _________. Small vessels that connect to the capillaries that carry blood back to the heart are ________. Vessels that carry blood back to the heart are _________.
Answer:
Small vessels that carry blood away from the heart to the capillaries are Arterioles. Muscular-walled vessels that carry blood away from the heart are Arteries. One-cell-thick microscopic vessels that function to exchange nutrients and wastes are Capillaries. Small vessels that connect to the capillaries that carry blood back to the heart are Venules. Vessels that carry blood back to the heart are Veins.
Explanation:
We have different types of vessels in our bodies. We can divide them by their size and structure. Starting from the ones that carry blood away from the heath, we have the arteries. Arteries are vessels of big diameter that have muscle around them. Then, the arteries branch into arterioles, which have a smaller diameter. The arterioles branch into capillaries. These are small vessels with thin walls that allow the exchange of nutrients, wastes, and gases with the neighboring tissues. Once that the blood flows through the capillaries, it goes to the venules, which are small veins that will carry the blood to the veins and these to the heart. The veins do not have muscles in their structures, and their walls are thinner than the ones in the arteries.

The image represents the mitosis process and it is important because:
A. produces gametes with half genetic information than parent cell.
B. allows processes as growing and repair tissues in the body.
C. does not produce cells with the same genetic information than parent cell.
D. always produce somatic cells with the same characteristics, it does not matter the organ in the body.
Answer:
B. allows processes as growing and repair tissues in the body.
Explanation:
Mitosis is a process where a single cell divides into two identical daughter cells. During mitosis one cell divides once to form two identical cells and the dividing cell's chromosomes are copied and then distributed equally between the two new nuclei of the daughter cells.
The major purpose of mitosis is for growth and to replace worn out cells. It also plays an important part in the development of embryos.
Mitosis is divided into five stages:
1. Interphase- during interphase, the DNA in the cell is copied resulting in two identical sets of chromosomes. Microtubules also extend from the centrosomes outside the nucleus
2. Prophase- during this phase, the sister chromatids in each chromosome pair up, the nuclear membrane dissolves and the mitotic spindle consisting of microtubules and other proteins extend across the cell between the centrioles which move to opposite ends of the cell.
3. Metaphase- the chromosomes line up at the centre of the cell and the mitotix spindle attaches to eachmof the sister c hromatids.
4. Anaphase- the sister chtomatids are pulled apart to each end of the cell by the mitotic spindle.
5. Telophase- at each pole, a full set of chromosomes gather together, a membrane encloses each chromosome, the cell pinches at the middle and then divides into two. This is known as cytokinesis.

Many different types of mutations can occur within the body. Cystic fibrosis is a genetic disorder that is caused by different mutations within the CFTR gene. One mutation in the CFTR gene that leads to cystic fibrosis causes translation to end earlier in the gene sequence. Which type of mutation causes this translation error that leads to cystic fibrosis?
Answer:
The type of mutation that causes this translation error is called deletion. Deletion occurs when a section of a DNA is deleted or lost. In cystic fibrosis, three nucleotides are deleted that results in the lost of phenylalanine

1. What conditions might cause the most water and sediment to be collected at the bottom of the stream table?
Answer: Steep, high velocity, no silting. The high water speed picks up silt from the bottom instead of letting it settle to the bottom. When the land gets level like often happens at the mouth of rivers where the water spreads out and slows down, silt settles to the bottom and you could get a wide, shallow delta.

Cardiac output is the amount of blood pumped by the heart in one minute. Which of these will increase cardiac output?
Answer: the factors that increase cardiac output include:
--> Nervous stimulation and
--> Hypertrophy of the heart.
Explanation:
Cardiac output can be defined as the quantity of blood pumped into the aorta each minute by the heart. This is also the quantity of blood that flows through the circulation. There are factors that can cause increased cardiac output or that can lead to a hypereffective heart. They are:
--> NERVOUS STIMULATION: The combination of sympathetic stimulation and parasympathetic inhibition does two things to increase the pumping effectiveness or cardiac output of the heart. These include:
• it greatly increase the heart rate from the normal level of 72 beats/mum up to 180 to 200 beats /mom.
• it increases the strength of heart contraction, which is called increased contractility to twice it's normal strength.
--> HYPERTROPHY OF THE HEART: A long term increased workload, but not so much excess load that it damages the heart, causes the heart muscle to increase in mass and contractile strength in the same way that heavy exercise causes skeletal muscles to hypertrophy. This effect of increased muscle mass of the heart, allows the heart to pump much greater than usual amounts of cardiac output.

Provide two reasons why it is important to isolate undigested plant cells.
I need this asap
Answer:
It helps to support growth and helps producing energy to do vital functions.
Hope this helps!
A reliable DNA analysis is based on the DNA conditions. The importance of using undigested cells is that DNA is well-preserved, not affected by external factors, and can be used to compare it to database sequences.
------------------------------------------
Dr. Pringle studies niche partitioning and competition reduction among coexistent species in Africa.
He is interested in knowing the exact source of food of different herbivorous species. To do so, he is using the technique of DNA metabarcoding.
He collects fresh animals' dung and gets the indigested plant cells.
DNA is isolated, sequenced, and compared with the DNI of known species, which are a potential source of food for these animals.
Once he matches the cells' DNA with the corresponding plant species from the database, he can use this information to detail the animal's source of food.
The importance of getting fresh, undigested cells from the dung, is that
The animal's digestive enzymes have not broken the cell walls and digested the cell content. The dung environmental conditions such as pH, temperature, or microbiota have not affected the cell's DNA. Undigested cells' DNA is well-preserved and can be used to compare it with the plant species database.------------------------------------------------------
