Answer:

Carbon Dioxide

Explanation:

I just know

The carbon dioxide is the gas molecule most likely in the dough. Thus, option C is correct.

Carbohydrates is defined as biomolecule that contains carbon hydrogen and oxygen in a ratio of 2:1. Carbohydrates are mane source of energy of the body they work as fuel for the brain, kidneys central nervous system and heart muscle. [tex]Cn(H2O)n[/tex] is the basic formula for all carbohydrates . But this formula have limitation i.e it applies where same amount of carbon and water are use.

Basically, the terms carbohydrate was used to describe compounds that have really contains carbohydrates. Because they had simple formula [tex]CH20[/tex]. In modern Era carbohydrates are classified on the basis of their structure not on their formulae. Such as aldehydes and ketones are now known as polyhydroxy.

Therefore, the carbon dioxide is the gas molecule most likely in the dough. Thus, option C is correct.

Answer:

Plants

Explanation:

The cell membrane is the plants.

Answer:

Ecosystems have carrying capacities, which are limits to the numbers of organisms and populations they can support. These limits result from such factors as the availability of living and nonliving resources and from such challenges such as predation, competition, and disease. If this helps you could I possibly have brainliest?

Explanation:

The impact of climate and lack of resources on the carrying capacity of an ecosystem is discussed below :

The carrying capacity of an ecosystem can be described as the maximum amount of organisms which can be naturally catered for giving the resources available in an environment.

Climate has an important role to play in the type of resource available or resources which can thrive in an environment. Similarly harsh climate conditions aren't favorable for survival, hence resulting in low carrying capacity of such ecosystem.

Also, organisms, animals depend on the available resources available in an environment for survival, when the available resources aren't enough to cater for a large population, the carrying capacity of the ecosystem is impeded.

Answer:

d. Unlike epithelial tissue, which is composed of cells closely packed with little or no extracellular space in between, connective tissue cells are dispersed in a matric

Explanation:

There are four primary types of tissues in living organisms. Epithelial and connective tissues are two of those four types of tissues. Epithelial tissues are made up of closely packed cells that serve functions such as absorption, secretion, protection, etc while connective tissues are composed of cells, ground substance, and protein fibers that serve supportive functions.

The cells of epithelial tissues are so closely packed to one another that there is hardly space in their extracellular matrix for materials. However, on the contrary, connective tissues are made up of cells that have room for large quantities of extracellular matrix. Hence, the cells that make up connective tissues are dispersed into matrix.

Your answer is CO-ENZYME!

Explanation:

What do CO-ENZYMES do?

They are an organic (but not protein based) compound...they act in a reaction by assisting the enzymes to bind and react with another substance...this then makes the reaction even faster!

But they cannot ever work by themselves to catalyse a reaction!

yes the human body is made of cells

Explanation:Cells are the basic building blocks of all living things. The human body is composed of trillions of cells. They provide structure for the body, take in nutrients from food, convert those nutrients into energy, and carry out specialized functions.Cells have many parts, each with a different function.

Answer:

Some of these sentences both refer to the same term.

1. The epithelial membrane that lines the closed ventral cavities of the body.  - 5. Makes up the pleura and pericardium. This is called the serous membrane.

2. The epithelial membrane that lines body cavities open to the exterior membrane . - 4. Found lining the digestive and respiratory tracts.  These statements refer to the mucous membrane.

3. Consists of keratinized stratified squamous epithelium.  - cutaneous membrane.

6. Lines blood vessels and the heart. - endothelium.

Explanation:

All of these membranes are formed by epithelial tissue - one of the four basic tissues found in the human body, with important tasks that many times give the organs they're part of their main function.

The epithelium can vary in shape and size in order to adapt to the necessities of the organ. If the organ needs protection from abrasions, like the skin or the stomach, this tissue will have many layers and be called "stratified epithelium". On the other hand, an organ with the function to exchange substances, like the blood vessels or the alveoli, will have only one layer of epithelium, to ease the diffusion of gases and other molecules.

The other three basic tissues are: connective tissue, muscle tissue, and nervous tissue.

Explanation:

The experimental data shows that the RhoBTB3 expression increased after 12 hours and reached it's peak at 18 hours, which occurs in the G2 phase. The expression of Cyclin E1, however, started to increase after 8 hours, peaked at 14 hours, and remained there for 2 more hours before starting to decline. This shows that the highest level of the Cyclin E1 expression occurred in the S phase and initiated at the end of the G1 phase. His hypothesis is incorrect because if RhoBTB3 signaling did regulate the production of Cyclin E1, then the peak should have occurred prior to Cyclin E1.

Bio

Bio means living or life, Biology is the study of life forms.

Answer:

The most probable location on the chromosome of each gene is:

wing shape gene ------- eye color gene -------- body color gene

Explanation:

To know if two genes are linked, we must observe the progeny distribution. In a tri-hybrid cross, If individuals, whos genes assort independently, are test crossed, they produce a progeny with equal phenotypic frequencies 1:1:1:1:1:1:1:1. If we observe a different distribution, that is that phenotypes appear in different proportions, we can assume that genes are linked in the heterozygote parent.

We can recognize the parental gametes in the descendants because their phenotypes are the most frequent, while the double recombinants are the less frequent. And simple recombinant gametes produced by the cross, which frequencies are intermediate.  

By comparing the parental and the double recombinant we will realize which is the allele that changes in position. The position of this gene is in the middle of the other two genes because in a double recombinant only the central gene changes position in the chromatid.

So, according to this knowledge and the available information in the problem we can estimate the position of the genes in the chromosome.

Phenotypic proportions:

90% of individuals are red-eyed and curly-winged. This is a high frequency, which means that this is the parental phenotype. The other parental phenotype must be white eyes and straight wings.

Flies with curly wings, white eyes, and black bodies represent the lower proportion (1%) so this phenotype must be the double recombinant.

Flies with red eyes and black bodies, and flyes with red eyes and brown bodies are intermediate in proportion, so they must be simple recombinant phenotypes.

Parental)

Red, Curly  

White, Straight

Double recombinant)

White, Curly, Black  

Red, Straight, Brown  

Simple recombinant)  

Red, Black

Red, Brown

In the chromatid, there are two regions, Region 1 (from the first gene to the gene in the middle), and region 2 (from the gene in the middle to the gene of the other extreme).

The fact that both simple recombinants are red, tells us that the eye color gene and the body color gene are together, and the recombination occurred either in region 1 or 2.  

We know that the double recombinant is White, Curly, Black. We also know that the eye color gene and the body color gene are together, so one of these two must be in the middle.

Parentals are red and curly, which means that the eye color gene and wing shape gene are also together. This leads us to assume that the eye color gene is in the middle.

Finally, the fact that the double recombinant is White, Curly, Black, and knowing that the eye color is in the middle and that both the extreme alleles change position, we can assume that the parental Red, Curly is also black, while the other parental is white, straight and brown. So:

Curly ------ Red ------Black (90%)

Straight ----- White ----- Brown

Curly -----White-----Brown

Straight-----Red -----Black (75%)

Curly----Red-----Brown (25%)

Straight ----White-----Black

Curly-----White------Black (1%)

Straight----Red------Brown
