Answer:

the baby is a male

Explanation:

if it were a female the it would be xx

Answer:

A is wrong, because that fact just simply is not true. There have been several other raced men and some women as well that made important contributions to science.

B is correct, because science isn't attributable to just the last couple of hundred years. In ancient times, people developed astronomy and medicine. This is also correct because it names females as part of the scientific contributions to society.

C is incorrect, because this fact is also completely false. Lots of important scientific discoveries have been made from before that, such as the invention of electricity (somewhat useful today I would guess:\) in 1879, which is much longer than 100 years ago.

D is also incorrect, because scientific knowledge is changing constantly, every minute, growing and expanding and changing to accomodate new knowledge and information that we've discovered.

Food proteins are used most efficiently when we : ( B ) consume enough carbohydrates and fats to meet our kilocalorie needs

Our kilocalorie needs vary between male and females. An average male needs about 2700 kcal per day while a woman needs about 2200 kcal per day to function properly. In order to meet this kilocalorie needs we have to consume the essential nutrients such as carbohydrates and fats and proteins.

Hence we can conclude that Food proteins are used most efficiently when we consume enough carbohydrates and fats to meet our kilocalorie needs

The three adaptations that angiosperms have is attractive aspects of flowers, such as aroma and colors, are artifices created by angiosperms.

There are also fruits with adaptations that allow them to be dispersed by the wind; others that have structures that make them able to float on water, being carried by currents over long distances; or that allow them to stick to the fur of animals and be moved to new regions.

In this case, baspects of flowers, such as aroma and colors, are artifices created by angiosperms to attract pollinating animals, such as bats, bees, birds, etc. These adaptations are a major survival advantage over other plant groups.

Nucleotides from the DNA template strand complement the mRNA's codons. These codons code for amino acids. Option B is correct. CAA - CTA - TCG

Nucleotides are monomers composed of a sugar molecule, joined with a phosphate group and a nitrogenated base.

Several nucleotides joint by their extremes compose the nucleic acids.

Nucleotides have a certain order or sequence in nucleic acids, which is significant since these sequences carry biological information neccesary to carry out cellular functions.

Codons are short sequences of three nucleotides that carry genetic information needed to build the protein. These units determine which amino acids are added to the growing chain during the assembly.

More than one codon might code for the same amino acid.

Different sequences of three nucleotides -codons- might code for a different amino acid. This means that the resulting proteins will not be the same, and they will accomplish different functions.

When DNA molecule unwinds to be transcripted, two single strands get separated,

It receives that name because it is the sequence that codes for each amino acid composing the proteins.

When referring to the coding strand, we are talking about the sequence that turns out to be the same as the mRNA that results from the transcription of the same DNI segment -switching bases T for U-.

This is the one that is used during transcription to synthesize mRNA. The template strand is the one that is going to be complemented by the mRNA.

To get to know the sequence of nucleotides in the template strand that code for the polypeptide sequence val-asp-ser, firts we need to know which codons code for these amino acids.

1)

Amino acid            Codon

Val                          GUU, GUC, GUA, GUG

Asp                         GAU, GAC

Ser                          UCU, UCC, UCA, UCG, AGU, AGC

These are all the possible codons in mRNA that might code for these amino acids. Now, we need to identify their complementary bases on the template strand.

2)

mRNA        Template strand

GUU                  CAA

GUC                  CAG

GUA                   CAT

GUG                  CAC    

GAU                   CTA

GAC                   CTG    

UCU                   AGA

UCC                   AGG

UCA                   AGT

UCG                   AGC

AGU                   TCA

AGC                   TCG  

The column of the right shows all the possible nucleotides that might complement the mRNA codons. There are several combinations. Now, we need to choose among the options the correct combination.

3)

Options A and  D  ⇒  guu-gau-agc and caa-cua-ucg

These are not the correct options since they carry uracils instead of thymines. Remember that DNA molecules have thymine, and RNA molecules have uracil.

Option C ⇒ gtt-gat-agc

This is not correct since these sequences do not complement the mRNA codons.

Option B ⇒ caa-cta-tcg

This is correct. You can find these nucleotide sequences among the options written before for the template strand.

Option B) CAA - CTA - TCG is the correct one.

Formation of a gas, formation of a precipitate and formation of a slightly ionized product are the cases for the completion of ionic reactions.

The three conditions under which ionic reactions can run to completion i.e. formation of a gas, formation of a precipitate and formation of a slightly ionized product.

K+(aq) + Br−(aq) + Ag+(aq) + C2H3O2−(aq) → K+(aq) + C2H3O2−(aq) + AgBr(s)

Mg2+(aq) + SO42−(aq) + Ba2+(aq) + 2NO3−(aq) → Mg2+(aq) + 2NO3−(aq) + BaSO4(s)

So we can conclude that formation of a gas, formation of a precipitate and formation of a slightly ionized product are the cases for the completion of ionic reactions.

An organism that feeds on dead and deteriorating organic stuff is referred to as saprophytes.

Saprotrophs are decomposers that live on or in dead organic matter and secrete enzymes and nutrients into the ecosystem. Fungi are one such example.

With the exception of weathering, which is removed by air, water, or other agents, the deceased organisms will remain the same without detrivores and saprotrophs.

Humans are gradually altering the climate and the earth's temperature through burning fossil fuels, destroying forests, and rearing animals.

Explanation:

This significantly increases the amount of greenhouse gases already present in the atmosphere, increasing the greenhouse effect and contributing to global warming.

Climate change is mostly caused by the greenhouse effect. Some gases in the Earth's atmosphere act as greenhouse glass, trapping heat from the sun and preventing it from escaping into space, causing global warming.

Cavities are caused by tooth decay — a process that occurs over time. Here's how tooth decay develops:

Plaque forms. Dental plaque is a clear sticky film that coats your teeth. It's due to eating a lot of sugars and starches and not cleaning your teeth well. When sugars and starches aren't cleaned off your teeth, bacteria quickly begin feeding on them and form plaque. Plaque that stays on your teeth can harden under or above your gum line into tartar (calculus). Tartar makes plaque more difficult to remove and creates a shield for bacteria.

Plaque attacks. The acids in plaque remove minerals in your tooth's hard, outer enamel. This erosion causes tiny openings or holes in the enamel — the first stage of cavities. Once areas of enamel are worn away, the bacteria and acid can reach the next layer of your teeth, called dentin. This layer is softer than enamel and less resistant to acid. Dentin has tiny tubes that directly communicate with the nerve of the tooth causing sensitivity.

Destruction continues. As tooth decay develops, the bacteria and acid continue their march through your teeth, moving next to the inner tooth material (pulp) that contains nerves and blood vessels. The pulp becomes swollen and irritated from the bacteria. Because there is no place for the swelling to expand inside of a tooth, the nerve becomes pressed, causing pain. Discomfort can even extend outside of the tooth root to the bone.
