Correct answer: A). a) A gene from an organism can theoretically be expressed by any other organism

The protein synthesis information in the DNA is found to be contained by the three base sequences. Proteins are made from a chain of amino acids, which are directed by the codons present in the DNA.

Each codon is specified for the synthesis of only one amino acid. However, some amino acids are specified by more than one codon.

The correlation between the amino acid and codon is known as genetic code and is the same for every organism on the earth.

Is the movement of water along the concentration gradient

Nuetrik [128]

Answer:

- Is the movement of water along the concentration gradient: Osmosis.

- Is the use of energy to move the particles against the concentration gradient: Active transport.

- Is the movement of particles by diffusion without energy: Simple diffusion.

- Is the movement of particles along the concentration gradient: Passive transport.

Explanation:

The mechanisms of cellular transport involve all the processes that the cell carries out to incorporate substances into its interior or send them to the extracellular space, through its semipermeable cell membrane.

<h3>- Osmosis</h3>

Is a type of transport that consists of the passage of water from a space with a lower concentration of solutes to one with a higher concentration, in order to reach equilibrium, following a concentration gradient.

The concentration gradient is given by the difference in concentration between two substances, which indicates the direction in which molecules, such as water, should move from one place to another.

<h3>- Active transport</h3>

Unlike passive transport mechanisms, which depend on a concentration gradient that determines the movement of particles, in active transport there are two characteristics that define it:

The passage of substances into the cell against a concentration gradient.

The use of energy to carry out this process.

In this case, the passage of substances through the cell membrane will be according to the requirements of the cell, or when they cannot pass through the membrane.

<h3>- Simple diffusion</h3>

According to the characteristics of the cell membrane, some substances can pass freely through it while others require special mechanisms. When a molecule is able to pass through the membrane without the use of special mechanisms or energy we speak of simple diffusion.

In a cell membrane, whose composition is by hydrophobic or non-polar lipid molecules, simple diffusion allows the passage of non-polar molecules, gases and alcohol.

<h3>- Passive transport</h3>

Refers to the mechanism of entry and exit of substances from the cell that does not require the use of energy.

The mechanisms involved in the passive transport of the cell are simple diffusion, osmosis, facilitated diffusion - which requires special conveyors or channels - and ultrafiltration, which depends on hydrostatic pressure. Examples of substances using this mechanism are lipid molecules, water and electrolytes.

I need help with these

snow_tiger [21]

Answer No 1:

The trait which is being studied in the cross is the height of the pea plant.

Answer No 2:

The two alleles for this trait are tall height allele which we can write as T and the allele for short height which we can write as t.

Answer No 3:

The allele for tall height is the dominant allele. We can say this because when a cross between a dominant homozyous and a recessive plant were made the offsprings resulted in the tall plants which is the F1 generation in the figure. As a dominant trait masks the recessive trait, hence we can say that the tall height allele is dominant over the short height allele.

Answer No 4:

The allele for short height t is recessive because as we can see the short height trait is being masked by the tall height trait in the F1 progeny. In F2 progeny, there are more number of tall height plants produced which further prove that short height is the recessive trait.

Answer No 5:

The F1 offsprings will have a dominant tall height allele, T, and a recessive short height allele, t. The dominant allele was inherited from the tall parent and the short height allele, t, was inherited from the recessive parent.

We can say that because the F2 progeny shows some plants to have short heights which is only possible if the F1 generation has heterozygous dominant (Tt) alleles.

Answer:

A. Morphology

Explanation:

Why is it A?

Because Morphology is, the branch of biology that deals with the form of living organisms, and with relationships between their structures. This means their structure helps their hunting.
