The chart below shows the three main types of plant tissues and associated tissues.
VARVARA [1.3K]

The plant tissues can be subdivided in the chart as Vascular Sclerenchyma Parenchyma Xylem Phloem. Thus, the correct option is D.

<h3>What role does the sclerenchyma play?</h3>

Sclerenchyma's primary job is to offer mechanical support. They are made up of lengthy, slender cells that have a thick lignified wall. They lack protoplast and are largely dead.

The complete chart and table are given in the image attached.

A basic permanent tissue known as parenchyma makes up a large portion of the ground tissues of plants, where vascular tissues and other tissues are attached. They are non-vascular and made up of undifferentiated, primitive living cells that have undergone modifications to carry out distinct tasks.

Xylem, along with phloem and cambium, is a key component of vascular tissue. Its primary functions include providing mechanical support and storage as well as moving water and solutes from the plant-soil interface to the stems and leaves.

Parenchyma cells, are also a component of phloem and are essential for the storage of water, non-structural carbohydrates, and storage proteins.

Please explain the difference between a frameshift mutation and a base substitution mutation.
harina [27]

Answer:

A frameshift changes every codon past it. A base substitution only changes one codon.

Explanation:

DNA is comprised of nucleotides (A, C, T, G) that make up amino acids. Every three bases is called a codon and represents an amino acid.

In a frameshift mutation, a nucleotide is either added or deleted from the sequence. This offsets the entire sequence after it because the reading frame shifts. Here's an example:

ACTGCTATCGTCATC

If another T is added in between the first and second codons, then every codon after will be changed.

ACT>T<GCTATCGTCATC

A substitution mutation is usually less severe, as it only alters one codon in the sequence. These occur when one nucleotide is replaced by another one. Here's an example:

ACTGCTATCGTCATC

Let's say the first G is replaced by a T.

ACT>T<CTATCGTCATC

As you can see, none of the other codons changed.

Typically, a frameshift mutation is considered worse than a substitution mutation.

Which heart chamber pumps unoxygenated blood out the pulmonary trunk?
yuradex [85]

The correct answer is: right ventricle

There are two types of blood circulation:

1. Pulmonary circuit or circulation is a system of blood vessels between the heart and the lungs. In pulmonary circulation, deoxygenated blood leaves from the heart’s right ventricle through the pulmonary artery to the lungs. Oxygenated blood from the lungs (CO2 is released and O2 is picked up during respiration) is transported through the pulmonary vein and returned to the left atrium of the heart.

2. System circulation than transports oxygenated blood from the heart’s left ventricle through the aorta and to the rest of the body. Oxygen-poor blood from all tissues is then returned through the veins back to heart.
