Gravity

Explanation:

Percolation is the process of a liquid slowly passing through a filter. It's how coffee is usually made. Percolation comes from the Latin word percolare, which means "to strain through." Percolation happens when liquid is strained through a filter, like when someone makes coffee.

Evaporation-the process of turning from liquid into vapor.

Condensation-water which collects as droplets on a cold surface when humid air is in contact with it.

and gravity- Gravity is the force of attraction between two objects, and Earth's gravity pulls matter downward, toward its center. It pulls precipitation down from clouds and pulls water downhill. The warm water near the surface of the ocean heats up with sunlight and evaporates, keeping the water cycle in motion.

Answers

Answer:

Alvin is propelled by _gas or diesel___ hydraulic thrusters and features an electrical system powered by lead-acid batteries.

Explanation:

Technically, this implies that Alvin is working on motor-assist mode, using a hybrid engine.  Alvin is, therefore, propelled by an internal combustion engine (given the presence of hydraulic thrusters) in addition to an electric motor, which uses energy stored in (lead-acid) batteries.  Alvin must be a robot.

what is the difference between phenotypes and genotypes​

Answers

Phenotypes are the physical makeup of a living thing and genotypes are the genetic makeup of the living thing

Answer:

Phenotype are physical traits a organism can inherit for example color, height, or body features are phenotype. Genotype are genetic traits that can be inherited for example personality, or behavior traits. So the primary difference between phenotype and genotype is that "phenotype are psychical characteristics while genotype is genetic."

What is the function of a pollen tube?
to lead sperm cells into the ovary
to create more pollen
to create sperm cells
to lead egg cells to the sperm cells

Answers

Answer:

The function of the pollen tube is to lead sperm cells into the ovary.

Explanation:

In angiosperms, the pollen tube is a structure formed when the pollen grain comes into contact with the stigma and germinates, producing a tubal extension that is related to the embryonic sac where the female gametophyte is found.

The function of the pollen tube is to conduct the male gametophyte —which is found in the pollen— to the embryonic sac, in order to come into contact with the oosphere and produce fertilization.

The other options are not correct because the pollen tube:

Do not create more pollen. Do not create more male spermatophytes. Does not lead the eggs to the male spermatophytes.

Answer: to lead sperm cells into the ovary .

Explanation: There needs to be a way for the sperm cells formed by the pollen's generative nucleus to reach the egg cells that are found in the ovary.

Thymine

Answers

Adenine pairs with thymine and Guanine pairs with cytosine. The numbers are not exactly the same because of the mutations that happen in DNA. Some of the DNA could be broken off or put somewhere else in the gene that would throw everything off, nothing is perfect. However in a perfect world, both adenine and thymine would have the same numbers.

2. What fluvial landform is A?

Answers

Answer:

The landform marked with A is an ox-bow lake.

Explanation:

In the image, we can see a river and another fluvial landform right next to it. The river is meandering, moving through the plain in a zig-zag manner. The landform next to it has a half-circular shape, and it seems as it has been attached to the river until recently. In fact, the landform next to the river has been a part of the river until recently, but because of moving too far away from the base it became detached.

The landform in question is an ox-bow lake. This is a lake that has a short lifespan, and it usually has a half-circular shape, being just a few meters away from the river from which it formed. Initially, the ox-bow lake was actually part of the river and its meandering, but as the erosion was moving the water further and further away from the base of the river bed, the water was moving harder and harder, so naturally, the water moves in a direction where it is easier to do so. Little by little, the river starts to move in another direction, closer to its base, and the part of the meander that went too far away gets detached, thus forming an ox-bow lake.

A researcher places part of a plant cell in a beaker of water. She observes that the plant leaves release bubbles of gas when she shines a light on the beaker, and this is due to the plants going through photosynthesis, which is in Option B.

What is the product and the bubble formation in photosynthesis?

The bubbles that are seen in water when plants are kept in light are actually oxygen bubbles. During photosynthesis, plants use sunlight, carbon dioxide, and water to produce glucose (sugar) and oxygen. The oxygen produced during photosynthesis is released into the surrounding environment as a waste product. When plants are submerged in water, this oxygen can accumulate and form bubbles. This process is called bubbling. The bubbles that are seen in the water are an indication that the plant is actively photosynthesizing and producing oxygen.

Hence, she observes that the plant leaves release bubbles of gas when she shines a light on the beaker, and this is due to the plants going through photosynthesis, which is in Option B.

Answers

Answer:

Increasing  carbon dioxide  concentration  increases the  rate of  photosynthesis  as carbon  dioxide (CO2) is a limiting factor.

Explanation:

Some limiting factors like carbon dioxide, temperature etc. influence the photosynthetic rate, which may end up reducing the potential amount of carbohydrate produced by photosynthesis. Carbon dioxide is important for this form of biosynthesis: it provides the inorganic carbon that is integrated into carbohydrate molecules.

The photosynthetic rate can be slowed by a decline in the concentration of available carbon dioxide.

Answers

Answer:

Speed of both will be decreases when they travel through the medium of water.

Explanation:

Both sunlight and radio wave has the same speed in vacuum but both speed will be decreases when they travel through the medium of water because the consistency of water is more than air which make hard to travel for sunlight and radio wave. The speed of sunlight is slightly decreases but the radio wave can't go too far in the water and finally stops so we can say that sunlight can travel through water but radio wave none.

Explanation:

Transcription is the process by which a strand of mRNA, needed to direct protein synthesis in the cytoplasm, is synthesized from a strand of DNA.

The sequence of nucleotides in the RNA chain depends on the sequence of bases in the DNA strand, being placed according to the complementarity of nitrogenous bases, where a purine is complemented with a pyrimidine.

In RNA, the thymine base is replaced by Uracil, the complementary base to adenine of DNA.
