e) missense mutation

Explanation:

Theoretical frame

Transcription occurs in the nucleus where the template DNI strand is read in direction 3´→ 5´ to build the mRNA molecule in direction 5´→ 3´.

When the DNI molecule separates into two strands to form the transcription bubble, we can identify two separate segments: coding strand and template strand.

The coding strand goes in direction 5´ to 3´, while the complementary strand -template strand- grows in direction 3´ to 5´.

The template strand is the mRNA complement.

The coding strand is the same as the mRNA that results from the transcription of the same DNI segment -switching bases T for U-.

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

Translation occurs in the cytoplasm. rRNA and tRNA read mRNA in the direction 5´→ 3´ to build the protein.

Genetic information for the aminoacids assembly during the protein synthesis is stored in short sequences of three nucleotides named codons in the mRNA. Each of the codons represents one of the 20 amino acids used to build the protein. There are 64 codons in total, from which 61 codify for amino acids. Because there are 20 amino acids, many codons code for the same amino acid. One of these amino acids is also the start point of protein synthesis. And the left three codons are stopping translation points.

The codons indicating the initiation or stop points during the translation process are:

• The start codon AUG is the most common sequence used by eukaryotic cells

• The end codons are UAA, UAG, UGA.

When a change occurs in a single base pair, it is known as a point mutation. Points mutations might be either silent, missense, or nonsense. In silent mutations, the resulting mRNA codon codes for the same amino acid as the unmutated sequence. However, if the mutation causes the mRNA codon to code for a different amino acid, this mutation is a missense mutation. Finally, if the mutation causes mRNA codon to be a stop codon, we are referring to a nonsense mutation.

----------------------------------------------------------------------------------------------------------

In the exposed example,

Before mutation

After mutation

This is a point mutation, in which the change occurs in a single base pair. The mutation made the mRNA codon code for a different amino acid, meaning that this is a missense mutation.

Answer:

Enzymes such as amylase ,protease and lipase are liable for solubilizing spare food materials in form of starch, protein and lipids correspondingly

in seed and deliver energy and other fundamentals food materials to germinating embryo.

The seed proteins are catalyzed by protease enzyme and break it into amino acid and peptides that a e transferred to growing embryo.

The amino acids obtained from metabolism of the proteins are further used in biosynthesis of enzymes,hormones,proteins, pyrimidines and Purine bases.

The starch is catalyzed by enzyme amylase that provides the food materials for growth and development of embryo . Similarly lipase are enzymes that are responsible for metabolism of the triacylglycerols into glycerols and fatty acids.This is also the source of energy for growing embryo

Answer:

In sexual reproduction gametes fuse to lead to new genetic combinations

Explanation:

In sexually reproducing organisms, there are two parents who create genetically diverse offspring.

This occurs because the gametes of the two parents combine to create very unique genetic combinations, which lead to increased genetic variation.

On the other hand, asexually reproducing organisms reproduce without a partner.

Their offspring are identical clones to the parent, so they have much less genetic variation.

So, the correct answer is that In sexual reproduction gametes fuse to lead to new genetic combinations.

Explanation:

I don't think theres anything to explain rlly hope this is correct tho

operation of SODIUM-POTASSIUM PUMP moves sodium ions out of the cell and potassium ions into the cell. The correct option is D.

When a cell membrane moves molecules or ions against a concentration gradient or against an electrical or pressure gradient, the process is called ACTIVE TRANSPORT. Different substances that are actively transported include:

--> sodium ions,

--> potassium ions,

--> calcium ions and

--> some amino acids.

There are two types of active transport which are divided according to the energy that is used to cause the transport. They include:

--> primary and

--> secondary active transport.

PRIMARY ACTIVE TRANSPORT

A typical example is the SODIUM-POTASSIUM PUMP( Na+ - k+). This is a transport process that pumps sodium ions outward through the cell membrane of all cells and at the same time pumps potassium ions from the outside to the inside. This pump helps to:

--> maintain the sodium and potassium concentration differences across the cell membrane

--> establish a negative electrical voltage inside the cells.

The mechanism or OPERATION of the pump involves the following steps:

--> two potassium ions bind on the outside of the carrier protein and three sodium ions bind on the inside,

--> ATpase of the carrier protein cleaves one molecule of ATP, splitting it to Adenosine diphosphate (ADP) and liberating a high-energy phosphate bond of energy.

--> this liberated energy then causes a chemical and conformational change in the carrier protein,

-->this leads to the extruding of three sodium ions (3Na+) to the outside and two potassium ions (2K+) to the inside.

Therefore in the operation of SODIUM-POTASSIUM PUMP moves sodium ions out of the cell and potassium ions into the cell. The correct option is D.

What is puberty?

Puberty is the time when your child moves through a series of significant, natural and healthy changes. These physical, psychological and emotional changes are a sign that your child is moving from childhood towards adulthood.

Changes in puberty include:

physical growth and development inside and outside children’s bodies

changes to children’s sexual organs

brain changes

social and emotional changes.

When does puberty start?

Puberty starts when changes in your child’s brain cause sex hormones to start being released from the gonads, which are the ovaries and testes.

This typically happens around 10-11 years for girls and around 11-12 years for boys.

But it’s normal for the start of puberty to range from 8-13 years in girls and 9-14 years in boys.

There’s no way of knowing exactly when your child will start puberty. Early changes in your child’s brain and hormone levels can’t be seen from the outside, so it’s easy to think that puberty hasn’t started.

Puberty can be completed in about 18 months, or it can take up to 5 years. This range is also completely normal.

Girls: key physical changes in puberty

In girls, these are the main external physical changes in puberty that you can expect.

Around 10-11 years

Breasts will start developing. This is the first visible sign that puberty is starting. It’s normal for the left and right breasts to grow at different speeds. It’s also common for the breasts to be a bit tender as they develop. If your child wants a bra, a soft crop top or sports bra can be a good first choice.

A growth spurt occurs. Some parts of the body – like the head, face and hands – might grow faster than limbs and torso. This might result in your child looking out of proportion for a while. On average, girls grow 5-20 cm. They usually stop growing at around 16-17 years.

The body shape will change. For example, a girl’s hips will widen.

The external genitals (vulva) and pubic hair will start to grow. Pubic hair will get darker and thicker over time.

Around 12-14 years (about two years after breast development starts)

Hair will start growing under the arms.

A clear or white discharge from the vagina starts several months before periods start. If the discharge bothers your child, you could suggest your child uses a panty liner. If your child says it’s itchy, painful or smelly, consult your GP.

Periods will usually start within 2 years of breast growth starting, but can take up to 4 years.

Boys: key physical changes in puberty

In boys, these are the main external physical changes in puberty that you can expect.

Around 11-12 years

The external genitals (penis, testes and scrotum) will start to grow. It’s normal for one testis to grow faster than the other. You can reassure your child that men’s testes usually aren’t the same size.

Pubic hair will start to grow. It will get darker and thicker over time.

Around 12-14 years

Your child will have a growth spurt. Your child will get taller and their chest and shoulders will get broader. Some parts of your child’s body – like their head, face and hands – might grow faster than their limbs and torso. This might result in your child looking out of proportion for a while. On average, boys grow 10-30 cm. They usually stop growing at around 18-20 years.

It’s common for boys to have minor breast development. If your child is worried by this, it might help your child to know it’s normal and usually goes away by itself. If it doesn’t go away or if the breasts seem to be growing a lot, consult your GP.

Around 13-15 years

Hair will start growing on other parts of your child’s body – under the arms, on the face and on the rest of the body. Leg and arm hair will thicken. Some young men will grow more body hair into their early 20s.

The hormone testosterone is produced, which stimulates the testes to produce sperm.

Your child might start having erections and ejaculating (releasing sperm). During this period, erections often happen for no reason at all. Just let your child know that this is normal and that people don’t usually notice. Ejaculation during sleep is often called a ‘wet dream’.

Around 14-15 years

The larynx (‘Adam’s apple’ or voice box) will become more obvious. Your child’s larynx will get larger and their voice will ‘break’, eventually becoming deeper. Some boys’ voices move from high to low and back again, even in one sentence.

Answer:

For girls, puberty typically occurs between the ages of nine and thirteen

For boys, puberty typically occurs between the ages of ten and fifteen.

An increase in hormones – estrogen and progesterone in girls and testosterone in boys – causes the changes that happen during puberty.
