Write the complementary strand to this DNA molecule on the line.
G А Т
ССА TG A G TT A CG

Answers

Answer:

If you mean the complementary strand of GAT: Answer is CTA

If you mean the strand for all of it (GATCCATGAGTTACG): Answer is CTAGGTACTCAATGC

Explanation:

Both strands always have to be in a sequence that pairs them to their nitrogenous base pair according to Chargaff's law. So always remember:

A pairs with T (Adenine with Thymine)

C pairs with G (Cytosine with Guanine)

Whenever you need to figure out the other strand, just switch the original base sequence with their base pairs to get the second strand/sequence.

Which characteristic best supports that an offspring is produced by sexual reproduction and not asexual reproduction?

Answers

Answer:

The offspring has the same number of chromosomes as its mother and father.

Explanation:

The child shares the same number of chromosomes with both parents. Two parents participate in sexual reproduction, which results in children with distinct genetic makeup.

What is sexual reproduction?

A diploid zygote is created during sexual reproduction when two haploid gametes combine during fertilization.

Asexual reproduction creates clones of the original parent, which results in kids that are genetically identical to the parent. Asexual reproduction allows for the rapid production of vast numbers of children by a single person.

This is due to the fact that in asexual reproduction, the only single parent produces an additional child that is genetically identical to the parent.

Therefore, the sexual mode of reproduction is seen to be superior to the asexual mode.

Answer:

what is the modifications of plants?

ans -In some plants, the roots change their shape and get modified to absorb and transport water and minerals from the soil to different parts of the plant. They are also modified for support, food storage, and respiration. The root modifications perform two major functions- Physiological and Mechanical.

Cell Division: Parts of Nephron

Leaf Structure: Genotype Meaning

2.why are different parts of plants modified?

ans-Certain parts of a plant undergo modification in order to adapt to their surroundings and environmental conditions. These modifications help them in their survival against odds. For example, the leaves in a cactus plant are modified to spines to reduce the surface area and hence water loss by evaporation.

Answers

Put the components of the visual projection pathway in order starting with the retina and ending with the brain. In order, starting from the lowest to the highest, we have:

Bipolar and ganglion cells of the retina Hemidecussation in optic chiasmOptic tracts Lateral geniculate nucleus (LGN) of the thalamusOptics RadiationPrimary visual cortex in the occipital lobe

The visual projection pathway is referred to as the channel through which electrical impulses created by the retina are transmitted to the brain.

When light penetrates the eye into the retina;

The bipolar and ganglion cells carry the signals from photoreceptors  (cones and rods) to ganglion cells, either actively or passively.

The axons of the ganglion gather and unite to form the optic nerve.

The optic nerve leads to the optical chiasm where hemidecussation of the optic nerve fiber takes place.

In the Optic Chiasm, the optic tract contains the nasal fibers that join from the left eye and connect with temporal fibers from the right eye, vice versa.

The lateral geniculate nucleus (LGN) which connects from the optic tracts has nerve endings that send optical radiation information from the superior visual fields to the inferior visual fields.

The primary visual cortex region is largely located on the occipital lobe of the medial brain surface, its function is to receive and process the optical radiation information sent from the (LGN).

Therefore, we can conclude that we understood the order, mechanism, and process in the visual projection pathway.

Answers

Answer:

The reason why they are eukaryotic is that:

- have nuclei

- organelle surrounded by a membrane called the nuclear envelope (where DNA is stored).

why they are advanced and specialized:

- They have power plants called mitochondria.

- these cells evolved into multicellular organisms.

- Eukaryotic cells carry out complex metabolic reactions that prokaryotes cannot.

Explanation:

Eukaryotic organisms are said to have an advanced cell because they contain membrane bound organelles.

Eukaryotic organisms

Eukaryotes are microorganisms that are made up of membrane bound organelles and whose nucleus is enclosed in a nuclear envelope.
