Answer:

The overall purpose of the light-dependent reactions is to convert light energy into chemical energy.

Hope this helps :)

Explanation:

The light dependent reaction of photosynthesis is the stage that has the function of converting light energy into stable chemical energy.

Photosynthesis as a chemical process occurs in two different stages: the light stage and the dark stage, so called because only the first is directly involved in the presence of sunlight.

Therefore, we can conclude that the light dependent reaction of photosynthesis is this biochemical stage of harnessing sunlight to obtain organic materials.

Answer:photosynthesis chlorophyll

Explanation: Animals cannot perform photosynthesis because they are not a plant. And chlorophyll is what makes a plant green and animals aren’t green and don’t have chlorophyll

Answer:

Nicotine

Explanation:

Tobacco smoke contains numerous toxic chemicals including organic carcinogens such as polycyclic aromatic hydrocarbons and aromatic amines, inorganic carcinogens such as polonium 210, and arsenic and toxic alkaloids such as nicotine. Nicotine extracted from tobacco has also been used as an insecticide.

Answer:

Flatworms are small, literally flat worms, which 'breathe' through diffusion across the outer membrane (Figure 2). The flat shape of these organisms increases the surface area for diffusion, ensuring that each cell within the body is close to the outer membrane surface and has access to oxygen.

Hydrolysis yields the breakdown of larger molecules into smaller one. For eg., Proteins upon hydrolysis produce amino acids.

Hydrolysis is a type of chemical reaction in which water molecule is utilized to break the larger molecule into smaller component.

The chemical bonds (one or more) present between the molecule is cleaved through water in such a way one compound receives the H+ ion while the other receives the OH- ion.

In hydrolysis reaction water is the main reactant while in dehydrogenation reactions, water is formed as a by-product.

Hydrolysis is commonly exhibited by digestive enzymes. The complex food particles are broken into simple and absorbable units through hydrolysis.

The macromolecules such as carbohydrates, fats and proteins are broken into simple sugars, amino acids, fatty acid and glycerol by hydrolysis.

Hydrolysis is also an important event in biodegradation. It thus keeps the pollution in check.

Therefore, hydrolysis is an important reaction in biochemistry.

Prevent Grain Weevils

Inspect all grains upon purchase.

Freeze grains for at least one week to kill any eggs.

Buy grains in small quantities and eat within a reasonable time.

Answer:

1- The polar section of a phospholipid is the part with the phosphate group. This is sometimes called the polar head of the molecule.

2- The phosphate group is the negatively-charged polar head, which is hydrophilic. The fatty acid chains are the uncharged, nonpolar tails, which are hydrophobic.

Answer:

Co2 is inorgainc

Explanation:

Something is only concidered if it has a carbon-hydrogen bond. Carbon dioxide or Co2 does not contain hydrogen so it is inorganic.

Answer:

The correct answer is - incomplete dominance

Explanation:

An incomplete inheritance or incomplete dominance is an inheritance pattern when the dominant allele of the particular trait is not able to completely mask the effect of the recessive allele and express the mixed or intermediate effect of both the alleles.

Since the gray color is the expression of the mix or intermediate character of both dominant and recessive alleles between black and white, incomplete dominance is the simplest way to explain the inheritance of this character.

High temperature conditions lead to a slower rate of weathering.

Answer:

High temperatures

Explanation:

Answer:

9 pm

Explanation:

A pulls into the station every 6 hours while B pulls into the station every 3 hours. Hence, for every time A pulls up, B must have pulled up twice.

They both pulled into the station at 3 pm. At 6 pm (3 pm + 3 hours), B would pull into the station while A would still be on the road. At 9 pm (3 pm + 6 hours), B will pull in once more while A will just be pulling up the first time since 3 pm.

Hence, the next time both trains will pull into the station at the same time would be 9 pm.

Explanation:

Aerobic respiration is a set of metabolic reactions that take place in the presence of oxygen, occurring in a cell to convert chemical energy into ATPs. Anaerobic respiration is a process of cellular respiration where the high energy electron acceptor is neither oxygen nor pyruvate derivatives.

Explanation:

To calculate the population density, you will divide the population by the size of the area. Thus, Population Density = Number of People/Land Area. The unit of land area should be square miles or square kilometers. You can use square feet or meters if you are finding the density of a smallish space.

Answer:

To form a wide range of compounds with other elements

Explanation:

The ability of carbon to gain four more electrons allows this chemical specie to form a wide range of compounds.

When carbon gains four electrons, it becomes isoelectronic with neon and then becomes a stable compound or molecule as it combines with other atoms.

This leads to the proliferation of carbon compounds that we find in nature. Carbon can easily for covalent compounds with other compounds also.

Answer:chain-link fence

Explanation:a cell membrane is partial permeable which means that it lets some substances through but not other.

Answer:

Chain-link fence

Explanation:

Cell membranes are barriers that decide which molecules enter and exit the cell, and how much of them come in. So things are able to pass through them.

If it were a brick wall, it would not let anything pass through.

So it is more like a chain-link fence, but with more control over what passes through it.

Answer:

Explanation:

Herbaceous plant are plants that lack woody stem, they include mostly annual crop and perennial crop.

The reduction in the population of herbaceous plant over the years is due to competition. The competition intensity is usually high due to limited supply of resource and the woody plant out compete the herbaceous plants leading to a gradual decline in the population.

Competition intensity is usually high during dry season when herbaceous biomass and soil water content were at the lowest level at this time the herbaceous plant finds it difficult to thrive well with the limited resource while the woody plant utilizes the little resource and keeps on thriving. All this reduce herbaceous population after several years of the field been abandoned.

Answer: sexual reproduction is the union of male and female gametes to form a fertilized egg, or zygote. The resulting offspring inherit one half of their traits from each parent. The process where haploid sex cells are created from diploid parents is called meiosis, and it occurs only in the reproductive organs.

Explanation:

i have advanced so this is what i got right

Answer: In sexually reproducing organisms, each parent contributes half of the genes acquired (at random) by the offspring. Individuals have two of each chromosome and hence two alleles of each gene, one acquired from each parent. These versions may be identical or may differ from each other.

Explanation:

an allergic reaction wouldn't hurt it would itch, but it depends on where the reaction has formed. but it says that she was scratching the area of concern making it bleed so yes that would hurt. Benadryl would be a good idea to get the reaction to calm down but you need to stop the girl from scratching the area otherwise it will get worse  i dont know if im right, im very sorry if its wrong
