Answer:
There would be no seasons.
Explanation:
The tilt of the Earth's axis is what causes seasons. Throughout the year, different parts of Earth receive the Sun's most direct rays. So, when the North Pole tilts toward the Sun, it's summer in the Northern Hemisphere. And when the South Pole tilts toward the Sun, it's winter in the Northern Hemisphere. If there was no tilt, the rays hitting the Earth would have minimal changes, meaning no seasons.

Bloodworms, which are the mature larvae of non-biting midge flies, are commonly found in and around bodies of water. Most types of bloodworms can live only in pollution-free, oxygen-rich environments. However, a few species thrive in environments with low concentrations of oxygen and high concentrations of nutrients and pollutants. From the changes in the bloodworm populations shown in the table above, what can be determined about how water in the stream has changed?
A. The water has become less polluted, as evidenced by the decrease in the number of bloodworm species present and the increase in bloodworm population density.
B. The water has become more polluted, as evidenced by the decrease in the number of bloodworm species present and the increase in bloodworm population density.
C. The water in the stream has become less nutrient-rich, as evidenced by the increase in bloodworm population density.
D. The water in the stream has become more oxygenated, as evidenced by the increase in bloodworm population density.

What is embedded in the phospholipid bilayer that helps in the movement of larger molecules ?
A.Channel/Transport proteins
B.Salt
C.Water
D.Fats
Answer:
[tex]\boxed {\boxed {\sf A. \ Channel/Transport \ proteins}}[/tex]
Explanation:
The phospholipid bilayer is also known as the cell membrane. It covers cells and regulates the transport of substances. Certain ones can pass and others cannot, depending on certain factors like size and polarity.
Smaller substances tend to diffuse or move across the membrane quite easily. However, larger molecules have a much harder time. Many depend on special proteins embedded in the membrane. These are called transport proteins and they form a channel so large molecules can still move in or out of the cell.
So, salt, water, and fats do not contribute to the movement of larger molecules, but channel or transport proteins do and choice A is correct.

abiotic
Explanation:
abiotic - nonliving components of an ecosystem that can affect the living organisms.
Temperature is a nonliving component and it affects the organisms that live within a certain environment.
Therefore the answer is Abiotic
Reasons its not the other answers:
Biotic factors must be living things
Temperature is not a living thing therefore Biotic cannot be the answer
Same with living, temperature is not living therefore the answer cannot be living.
Temperature plays a huge role in an ecosystem therefore it is considered an important component and the answer cannot be unimportant.

A que se llama tierra de usufructo???
Ayuda
Answer:El usufructo (del latín: usus fructus, «uso del fruto»)1 es un derecho real de goce o disfrute de una cosa ajena. El Código Civil de España define este derecho en su artículo 467 como "el derecho a disfrutar los bienes ajenos con la obligación de conservar su forma y sustancia, a no ser que el título de su constitución o la ley autoricen otra cosa" .2 Por consiguiente, la persona titular del usufructo es mero tenedor respecto de la cosa pero no su dueño ni poseedor. Tiene la mera tenencia sobre la cosa, pero no la propiedad. Puede utilizarla y disfrutarla, es decir, obtener sus frutos o rendimientos, sean en especie o dinerarios, pero no puede disponer libremente de ella por no ostentar el derecho de propiedad sobre aquella. Es la razón de que no pueda enajenarla ni disminuir su valor sin el consentimiento del titular de la propiedad.

Genes influence an organism's traits by coding for ?
A:
Cells
B:
Proteins
C:
Chromosomes
D:
DNA
Genes influence an organism's traits by coding for proteins. Therefore, option B is correct.
What are genes?Genes are segments of DNA that hold the instructions needed to create a single, usually protein-producing, molecule in your body. These proteins regulate how our body develops and functions; they are also in charge of determining many of our physical traits, like our eye color, blood type, and height.
the information connected to a certain characteristic of the organism is encoded by these on the strands of genomic material; the entire strand of DNA or RNA is made up of numerous genes, each of which contains information. DNA is converted into RNA and then RNA is converted into protein.
Genes influence an organism's traits by coding for proteins. Therefore, option B is correct.
