This is for biology, I’ve been having some trouble on it please help!

Answer:

The answer should be C

Explanation:

The egg contributes all the cytoplasm and organelles to the zygote. The sperm only contributes one set of chromosomes.

The typical sperm midpiece contains approximately 50-75 mitochondria with one copy of mtDNA in each. This represents an 8- to 10-fold decline in copy number during spermiogenesis.

Answer:

DNA is accidentally moved from one bacterium to another by a virus

Explanation:In transformation, a bacterium takes up a piece of DNA floating in its environment. In transduction, DNA is accidentally moved from one bacterium to another by a virus. In conjugation, DNA is transferred between bacteria through a tube between cells.

Tastes associated with caffeine, quinine, or aspirin are detected primarily

by bitter taste receptors.

These receptors can either be TAS2Rs or T2Rs  and they help to protect

against harmful food substances. They are also responsible in the

stimulation of hormones which increases hunger.

Bitter taste receptors are found in the oral cavity and stomach and it is the

receptor which bind to more than fifty percent of all the drugs  

manufactured.

It insulates the axon and assembles specialized molecular structure at the nodes of Ranvier. In unmyelinated axons, the action potential travels continuously along the axons.

For example, in unmyelinated C fibers that conduct pain or temperature (0.4–1.2 μm in diameter), conduction velocity along the axon is 0.5–2.0 m/s (as fast as you walk or jog).

parasympathetic ganglion.

Acetylcholine is the main neurotransmitter found in the parasympathetic

nervous system. Its effects are either excitatory or inhibitory. It is a chemical

which is released by neurons to aid transmission of signals to other cells of

the body.

It helps in the contraction of the muscles, peristaltic movement of the

stomach, as a vasodilator etc.

Answer:

A series if reaction break and rrarrange csrbon bonds to release energy ang carbon dioxide.

The correct sequence of energy extraction from glucose is 5, 1, 2, 3, 4 to complete the oxidation of glucose.

Thus, the phases of cellular respiration should be performed in the following order: Krebs cycle, oxidative decarboxylation, electron transport chain, and oxidative phosphorylation are the steps in glycolysis.

The process of energy extraction from glucose:

When the bonds in 6-carbon glucose are broken and reorganized into 3-carbon pyruvic acid molecules, a little amount of energy is produced. Pyruvic acid enters the mitochondrion from the cytoplasm.

Carbon bonds are broken and rearranged in a sequence of events that release energy and carbon dioxide.

Every pair of high-energy electrons travels through the electron transport chain resulting in the production of three molecules of ATP. One glucose molecule releases roughly 36 ATP molecules in total.

Therefore,  the process of energy extraction from glucose start from pyruvate forming and end with the ATP formation.

Answer: Like humans, dogs need to keep themselves cool to protect their bodies. They do sweat, but not in the same way. They only have sweat glands only on the paw pads and nose leather. Since they are covered with fur, it is more challenging to keep their bodies cool.

After your dog runs around, you will notice that he begins to pant heavily. Dogs rely on panting to keep their bodies cool. Panting causes the evaporation of water from the nasal cavity, tongue, throat and lungs, which helps lower their body temperature.

They also experience the same dilation in blood vessels as humans, which brings blood to the surface of the skin, allowing the air in the environment to cool them.

Any dog is at risk for heat-related problems, especially in warm, humid weather. Our brachycephalic friends are at a much greater risk than their long-nosed counterparts. Large breeds with thick coats, such as Bernese Mountain dogs or Pyrenees are also more prone. Dogs with pre-existing heart conditions or respiratory issues are also more likely to be overcome by the heat.

When these dogs pant to try and cool themselves, they have to work harder to do so. This only raises their body temperature even higher, making it worse instead of better.

Answer:

use "if...then...because"

Explanation:

a good way to write a hypothesis is using "if, then, because" statements because it fully explains your idea. you also need to make sure that your hypothesis is testable and realistic.

Jimothy is testing if jazz music effects bee honey production. he writes this statement:

If jazz is played near a bee hive while producing honey, then the bees will produce more honey because the smooth music will raise their dopamine levels so that they become happier and therefore faster and more productive.

Answer:

I will write some tips in my explanation!

Explanation:

After formulating wh questions, it's time to form a hypothesis or an educated guess, but how do we do this?

First, you must gather the knowledge you already know; ad back it up with something that has happened like a study, article, etc

Example: It is a known fact that distilled water does not contain impurities, in fact, many distilled water companies boast about their water being clean and safe.

This will be the base of your hypothesis, and from here, just add the knowledge of which you know that can make up a well supported hypothesis, which you will then test.

Example:

It is a known fact that distilled water does not contain impurities, in fact, many distilled water companies boast about their water being clean and safe. Because distilled water is free of impurities, we can say that it cannot conduct electricity, but if we add salt to distilled water, the water will then be able to conduct electricity because...
