Answer:

The correct answer is - brown heterozygous Bb and blue eye bb.

Explanation:

In the provided question it is given that there are 20 babies born, 10 babies had blue eyes and 10 had brown eyes. As it is known that brown eyes are dominant over blue eyes, therefore, on the basis of this we can say that all blue-eyed babies have a bb genotype and as brown eyes are dominant traits babies must have at least one copy of the B allele which represents brown eye trait.

case1:

Parent 1 : bb

parent 2: BB

   B      B

b  Bb   Bb

b   Bb   Bb

there are 100% brown eye offspring so this is not the case

case 2:

Parent 1 : bb

parent 2: Bb

   B      b

b  Bb   bb

b   Bb   bb

here, 50% brown eyes and 50% blue eyes offspring produced thus, the parent trait will be brown heterozygous and blue eye.

Explanation:

The processes that considerably turn carbon compounds into the atmosphere are the decaying of organisms, the respiration of animals, and emissions from automobiles and factories. Thus, the correct options for this question are B, C, and E.

The carbon cycle may be defined as a type of biogeochemical cycle through which carbo and its derivative products are exchanged among the various spheres of the earth's surface. Carbon is considered one of the main components of biological systems.

In the carbon cycle, rhe process of photosynthesis utilizes the carbon from the atmosphere in order to produce chemical energy in the form of glucose. While the excretion of animal waste products is responsible for nitrogenous compounds like urea or ammonia.

Except for these two, all other options are directly liberating carbon into the atmosphere which can easily be demonstrated in the carbon cycle.

Therefore, the correct options for this question are B, C, and E.

Umm every sense of organs travels in the spinal cord.

Most nerves of one of the sense organs go to the spinal cord before they go to the brain, and that organ is the one that is involved in the reflex action because it happens in a very short time and is controlled by the spinal cord before the brain..

Reflex actions are important because they allow the body to respond quickly to stimuli without waiting for the brain, and they can be especially important in situations where a quick response is necessary to avoid danger, such as when the hand touches hot substances and the hand suddenly goes back, which is due to the motor neuron action of the spinal cord.

Hence, most nerves of one of the sense organs go to the spinal cord before they go to the brain, and that organ is the one that is involved in the reflex action because it happens in a very short time and is controlled by the spinal cord before the brain.

Answer:

The amount of CO2 found in the atmosphere varies over the course of a year. Much of this variation happens because of the role of plants in the carbon cycle. Respiration happens all the time, but dominates during the colder months of the year, resulting in higher CO2 levels in the atmosphere during those months.

Answer:

Animals in space originally served to test the survivability of spaceflight, before human spaceflights were attempted. Later, other animals were flown to investigate various biological processes and the effects microgravity and space flight might have on them. Bioastronautics is an area of bioengineering research which spans the study and support of life in space.

Explanation:

Example 1: Albert II became the first monkey in space on June 4, 1949. He reached an altitude of 83 miles (134 km), but died on impact when the parachute failed. A previous monkey, Albert I, died when the V-2 rocket failed before reaching peak altitude. Two other monkeys, Albert III and IV, also died when their rockets failed.

Example 2:A mouse launched on Aug. 15, 1950, attained an altitude of 85 miles (137 km), but died when the rocket disintegrated due to parachute failure. Several other mice were launched during the 1950s.

Example 3 (and the most important example): Laika became the first living being to orbit the Earth on Sputnik 2, Nov. 3, 1957. She died several hours into the flight from stress and heat.

Middle size sediment will be deposited on the ground when the speed of flowing water decreases.

When a stream's velocity decreases from 300 to 200 centimeters per second, the middle size sediment will be deposited because of the lowering velocity of the stream. Big size sediments hardly move by the water of the stream.

While on the other hand, middle and small sized sediments easily moved by the flowing water due to their light weight so we can conclude that middle size sediment will be deposited on the ground when the speed of flowing water decreases.

Answer:

Acetone

Explanation:

Answer: Acetone.

Explanation: Acetone molecules have a polar carbonyl group that allows them to ACCEPT hydrogen bonds from OTHER compounds. The slightly positive charge on each hydrogen can attract slightly negative oxygen atoms on other water molecules, forming hydrogen bonds. If acetone is added to water, acetone would completely dissolve.

(1) Addition of the first GlcNAc oligosaccharides to the asparagine residue of a protein occurs in the Lumen of the Endopslamic Reticulum

(2) Synthesis of phosphatidylcholine occurs in the Endoplasmic Reticulum

(3) Degradation of misfolded ER protein ossurs in the Lysosome

(4) O-linked glycosylation occurs in the Golgiapparatus

Explanation:

1. The covalent attachment of a carbohydrate to a macromolecule such as proteins or lipids is known as glycosylation.

N-linked glycosylation is a very common form of glycosylation and it occurs in eukaryotes in the lumen of the endoplasmic reticulum.

The addition of the first GlcNAc oligosaccharides to the asparagine residue of a proteinmos an example of N-linked glycosylation.

2. Phosphatidylcholine is synthesized through the CDP-choline pathway which occurs at the cytoplasmic face of the endoplasmic reticulum. Choline entering the cell is immediately phosphorylated by choline kinase, converting choline to phosphocholine.

Phosphocholine is then converted to CDP-choline by the second enzyme in the pathway, CTP:phosphocholine cytidylyltransferase (CT).

The phosphocholine moiety is then added to diacylglycerol in a reaction catalyzed by CDP-choline:1,2-diacylgylcerol cholinephosphotransferase to complete the synthesis of phosphocholine.

3. Lysosomes are the cell organelles which are responsible for the breakdown of proteins as well as other components of the cell. Misfolded proteins are identified and transported to lysosomes through chaperone-mediated autophagy, macroautophagy and endocytosis, where they are then degraded.

4. O-linked glycosylation is a form of glycosylation that occurs in eukaryotes in the Golgi apparatus.

A ligament is a fibrous connective tissue which attaches bone to bone.

What is tendons and its function?

A tendon is a cord of strong, flexible tissue, similar to a rope. Tendons connect your muscles to your bones. Tendons let us move our limbs. They also help prevent muscle injury by absorbing some of the impact your muscles take when you run, jump or do other movements.

What is ligament and its function?

Ligaments often connect two bones together, particularly in the joints: Like strong, firmly attached straps or ropes, they stabilize the joint or hold the ends of two bones together. This ensures that the bones in the joint don't twist too much or move too far apart and become dislocated.
