Answer:

Fibrinogen

Explanation:

Fibrinogen is one of the proteins present in the blood plasma. It makes 7% of the plasma proteins. During the process of blood clotting, the active thrombin enzyme serves to convert soluble fibrinogen into insoluble fibrin. These insoluble threads of fibrin form the clot. Both thrombin and fibrinogen are produced in the liver. If fibrinogen is less than 4%, the process of blood clotting will be disturbed due to the production of insufficient threads of fibrin.

What is the relationship between blood vessel length and blood flow?

elena55 [62]

The length of a vessel is directly proportional to its resistance: the longer the veessel, the greater the resistance and the lower the flow. As with blood volume, this makes intuitive sense, since the increased surface area of the vessel will impede the flow of blood.

A random mutation occurs and the GGA codon is changed to GGU. What effect does this substitution have on the amino acid being ca

salantis [7]

Answer:

Instead of arginine codon, proline condon would be coded.

Explanation:

GCA encodes codes for glycine while on the other hand codon to GGU, GGC, or GGG encodes for glycine.

This substitution will lead to generation of complementary code “Proline” in the complementary mRNA or DNA strand.

The codon CCT, CCC, CCA, CCG encodes for proline. If this mutation would not have occurred then Arginine would have been encoded in the complementary codon with base structure of CGT, CGC, CGA, CGG

HELP ASAP I WILL GIVE BRAINLIST

Answer:

1) CO₂

2) 0.2551 g

Explanation:

The balanced reactions are:

CaCO₃ + 2HCl → CaCl₂ + H₂O + CO₂

MgCO₃ + 2HCl → MgCl₂ + H₂O + CO₂

1) The gas produced is CO₂.

2) Calculate mass of CaCO₃:

(0.5236 g) (0.4230) = 0.2215 g CaCO₃

Convert to moles:

(0.2215 g CaCO₃) (1 mol / 100.1 g) = 0.002213 mol CaCO₃

Find moles of CaCO₃:

(0.002213 mol CaCO₃) (1 mol CO₂ / mol CaCO₃) = 0.002213 mol CO₂

Convert to mass:

(0.002213 mol CO₂) (44.01 g / mol) = 0.09738 g CO₂

Calculate mass of MgCO₃:

(0.5236 g) (0.5770) = 0.3021 g MgCO₃

Convert to moles:

(0.3021 g MgCO₃) (1 mol / 84.31 g) = 0.003583 mol MgCO₃

Find moles of MgCO₃:

(0.003583 mol MgCO₃) (1 mol CO₂ / mol MgCO₃) = 0.003583 mol CO₂

Convert to mass:

(0.003583 mol CO₂) (44.01 g / mol) = 0.1577 g CO₂

Total mass of CO₂:

0.09738 g CO₂ + 0.1577 g CO₂ = 0.2551 g CO₂

The McDonald Kreitman tests of genes in the human and chimpanzee genomes showed many with an excess of nonsynonymous variation w

kondaur [170]

Answer:

A mutation may be bad and good depending on the particular environmental conditions

Explanation:

For example, the falciform anemia is a hereditary disease caused by a mutation where the ability to transport oxygen of red blood cells is reduced; however, this genetic disorder is widespread in some African populations because it is a condition that confers resistance to falciparum malaria. In consequence, falciform anemia is a detrimental mutation that may also be beneficial in endemic malaria regions.

Moreover, it is important to note that the higher proportion of non-synonymous substitutions are not subject to selection (only a minor percentage are positively selected) because they are generally localized within non-coding regions, thereby having neutral status.
