Water flows through a selectively permeable membrane in a process called __________, but water molecules cross the membrane more easily through channels of transmembrane proteins called __________.
Answer:
Osmosis
Aquaporins
Explanation:
This is because osmosis is the movement of solutes from a region of lower concentration to a region of higher concentration through a permeable membrane.
Aquaporins are lipid bilayer and water pores that serve as channels of transmembrane proteins that allow water to cross the membrane very fast, and they play vital roles red blood cells, plant cells and kidney which help to reduce water lose.
What gets passed through the electron transport chain and both photosystems to create energy?
A. electrons
B. oxygen
C. pigments
D. ATP
Answer:
A. electrons
Explanation:
Energy in form of ATP is generated at both cellular respiration and photosynthesis. In cellular respiration, energy (ATP) is synthesized in the mitochondria when ELECTRONS (e-) passes through series of complexes composed of proteins called ELECTRON TRANSPORT CHAIN.
On the other hand, ATP is synthesized when ELECTRONS produced from splitting water i.e photolysis of water, passes through photosystems 1&2 in the chloroplast (thylakoid).
Answer: Electrons
Explanation: The electron transport chain is a series of molecules that accept or donate electrons easily
The resting potential of resting neuron is caused by ________.A.A higher concentration of Na+ on the outside of the cell making it more positive outside.B.A higher concentration of Na+ on the inside of the cell making it more positive inside.C.A higher concentration of K+ on the outside of the cell making it more negative outside.D.A higher concentration of K+ on the inside of the cell making it more positive inside.
The resting potential of a resting neuron is caused by a higher concentration of Na+ on the outside of the cell making it more positive outside. So, it's A.
What do you mean by Resting potential?Resting potential may be defined as a condition of the imbalance of electrical charge that exists between the interior of electrically agitated neurons and their surroundings.
During resting potential, the passive efflux of K+ ion is more than the influx of Na+ ions. This imbalance makes the inside of the cell more negative as compared to the outside.
Therefore, the correct option for this question is A.

what do the results suggest about ways that milkweed bug populations are limited in nature?
Answer:
Temperature.
Explanation:
Temperature was the only limiting factor that controls and limits the size of the population of milkweed bug in the nature because these milkweed bug are very sensitive to temperature. Little increase or decrease in temperature can cause adverse effect to the population f milkweed bug in that environment. Milkweed bugs need food, water, space, shelter and a mate in order to survive a well as increase in population of milkweed bug.

Mendel worked with pea plants, which are usually (cross-pollinating / self-pollinating). When he transferred pollen from one pea plant to another, he was (cross-pollinating / self-pollinating) the pea plants to (fertilize / segregate) the eggs and form embryos within a seed.
Answer:
1. self-pollinating
2. cross-pollinating
3. fertilize
Explanation:
Gregor Mendel was an Austrian monk regarded as the Father of Genetics due to his immense contribution to discovering the patterns of inheritance. During his lifetime, Mendel worked with garden pea plants (Pisium sativum). One of the notable reasons he worked with peas is their ability to SELF-POLLINATE.
However, Mendel transferred pollen from one pea plant to another in a process called CROSS-POLLINATION. In cross-pollination, the pollen from one plant is transferred to another plant in order to FERTILIZE the egg and form embryos within a seed.
13. If a stream or river stops flowing due to water scarcity, what disease may result from the stagnant water?
malaria
hunger
sickle cell anemia
lung cancer
If a stream or river stops flowing due to water scarcity, the disease that will be caused by the stagnant water is malaria. The correct option is A.
What is malaria?Malaria is a disease that is caused by a protist, called plasmodium. It has four species and all give malaria. It is transmitted by mosquitoes because plasmodium lives in mosquitoes.
Stagnant water is stored water in a place for a very long time. The water of a river or s stream is stopped by dams sometimes. This water is the home to many insects to lay their eggs, like, mosquitoes.
Mosquitoes lay their eggs in water bodies or stop water, so they will lay their eggs in the stagnant water. It will increase the population of mosquitoes and with the increase in mosquitoes, there will be an increase in the cases of malaria.
Thus, the correct option is A. malaria.

why is it important for plant's to store food?
Answer:
Storing the food helps them to use it in winter and survive because there is very little sunlight available and so they photosynthesis less. ... When they have extra food they store it in their seeds and when the seed grows it gets it's food from the plant until the plant is able to photosynthesis and produce its food.
Answer:
It's important for plants to store food, as food is a source of nutrition, which is necessary for survival. Rather than just eating the food, storing it is a good way to ensure nutrients during droughts or other harsh conditions that make it hard to find food.

How many genders are there?
Answer:
Nobody really knows how many genders there are.
Explanation:
It widely depends whether you're referring to actual genders or gender identity types. Even then, though, there is not a definite or limited amount of either. For more clarification about the differences...
Gender identity types include: transgender, nonbinary, agender, demigender, etc.
These are not genders because they don't specify what you identify as, they are simply stating that you do not identify with your sex at birth. Don't call these genders, because that would be putting agender and nonbinary people into a binary.
Actual genders include: two-spirit, pangender, polygender, etc.
These are GENDERS rather than gender identity types because they somewhat specify what you identify as.
To say that there are only two genders is incorrect, as gender is a social construct. That does not mean it's useless, it just means that it wasn't constructed correctly because nobody knows for a fact how many genders and gender identity types there are and we probably never will because it's based on one's individual feelings.
Answer:
alot. if you are talking about what you are born with (sex) then there is 3. which is male, female, and intersex. GENDER is completely different. there is too many that i can even say but you can be a girl, a boy, somewhere on the non-binary spectrum (non-binary, demigender, agender, gender fluid, ect), ect.
