PLEASE HELP!! <br><br> How is a karyotype useful?
Firlakuza [10]
Karyotyping can be used to detect a variety of genetic disorders. For example, a woman who has premature ovarian failure may have a chromosomal defect that karyotyping can pinpoint. The test is also useful for identifying the Philadelphia chromosome. Hope this helps :)

What do deep roots do for the plant
aksik [14]

Answer:

Here you go :)

Explanation:

Plant roots complete a cycle in the soil. The deeper they go, the more benefits they provide to soil fertility and stable carbon storage in soils. While alive and active, roots redistribute carbon and nutrients throughout the soil profile.

Which part of the nervouds system consists of the brain and spinal cord:
Damm [24]

Answer:

c. CNS

Explanation:

The Central Nervous System (CNS) is responsible for receiving and transmitting information throughout the body. We can define it with the command center that coordinates the activities of the body.  It consists of the brain and spinal cord, which are protected by the skull and spine respectively.

Both structures are reinforced by three connective blades, called meninges. They are: dura mater, arachnoid and pia mater. Between the last two there is a fluid that is responsible for the nutrition of the CNS and the minimization of possible trauma caused by mechanical shocks.

Which processes are involved in the chloroplast of a plant cell?
Ahat [919]

Answer:

Chloroplast absorbs sunlight and it is used to make feed for the plant together with water and carbon dioxide gas. Chloroplasts are used to generate the free energy stored in ATP and NADPH via a photosynthesis process.

Explanation:

The site of photosynthesis action is chloroplast within a plant cell consisting of two chlorophyll molecules (PS1 and PS2), which have been embedded in the thylakoid membranes. The chloroplast consists of two chlorophyll molecules (photosynthetic pigments responsible for the green color of chloroplast). Each chlorophyll molecule absorbs light, caused to depart the chlorophyll molecules. This absorbs two electrons from each phenotype. PS2 electrons pass through the transportation chain for electron carriers, a series of redox reactions that release the energy used to synthesize ATP via Photophosphorylation/Chemiosmose (as the H+ ions diffuse through the stalked particles ATP, which changes the shape and catalysts, the electrochemical gradient diffuses down through the stalky particle ATP synthase).

Then these electrons replace the electrons lost in PS1. PS2 electron is replaced by photolysis electron, which when light strikes chloroplast, splitting the water into oxygen gas, H+ ions, and electron enzymes in the thylakoid space are catalyzed. The PS1 electrons combine to create NADPH with H+ ions and NADP (reduced NADP). These are the light-dependent photosynthetic reactions in chloroplasts. In the light-independent reactions, the NADPH and ATP are created. A pile of thylakoids is known as granum.

The light-independent processes take happen in the stroma. This is the site of carbon fixation; CO2 reacts with RUBP to generate GP (glycerate-3-phosphate) which is catalyzed by the enzyme RUBISCO (the most abundant enzyme in the world) (the most abundant enzyme in the world). The NADPH and ATP from the light-dependent processes convert GP to GALP (glyceraldehyde 3-phosphate). Two out of every 12 GALP molecules produced are used to synthesize glucose that can be employed either in breathing or in cellulose-forming condensation polymerization to add extra strength to the planted cell wall. The other GALP molecules are returned to RUBP.
