carbon has four valence electrons, so it can achieve a full outer energy level by forming four covalent bonds. this special ability allows carbon to do what?
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.
How does oxygen enter the cells of the tube worm
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.

Carbon dioxide, Co2, contains carbon, yet it is considered to be inorganic. Explain.
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.

Explanation:
Suppose you mate a black rooster with a white hen. The feathers of all the offspring are "gray," a color that is intermediate between black and white. Explain the inheritance pattern in these chickens.
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.

its not a sign because thats just something she is telling you, everything else is something you can see
Answer:
she is bleeding
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

By 40-60 years after farm fields had been abandoned, the amount of herbaceous plants decreased. Give one reason why the amount of herbaceous plants decreased as the amount of trees increased.
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.

What are the products of the hydrolysis reaction?
Hydrolysis yields the breakdown of larger molecules into smaller one. For eg., Proteins upon hydrolysis produce amino acids.
What is hydrolysis?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.

Which statements explain the relationship between photosynthesis and cellular respiration? Check all that apply.
The glucose that plants use for energy is made by animals in cellular respiration.
Glucose is a reactant in both photosynthesis and cellular respiration.
The oxygen released by photosynthesis is breathed in by animals to break down glucose.
Carbon dioxide is a product of both photosynthesis and cellular respiration.
The carbon dioxide released by animals is used to build glucose in photosynthesis.
Answer:
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.
Is a cell membrane more like a brick wall or a chain-link fence? Why?
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.

Train a pull into the sation every 6 hours . The train B pulls into the sation every 3 hours . They both pulled thr sation at 3pm. When is the next time they with both pull into the sation at the same time?
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.

What is the primary function of the light dependent reaction of photosynthesis
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.
During this phase, bioluminal reactions take place inside the plant, that is, the plant captures solar energy through chlorophyll and uses it to produce ATP and NADPH.Therefore, we can conclude that the light dependent reaction of photosynthesis is this biochemical stage of harnessing sunlight to obtain organic materials.

Describe how traits are inherited through traits sexual Reproductions
WILL MARK AND 5 STARS
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.
