Explanation:

There are 3 possibilities for the genes: AA, Aa, aa.

in both AA and Aa, there is a dominant gene present. If a dominant gene is present, it will always show the dominant trait.

In aa, there is no dominant gene present, and there are only recessive genes. Because of this, the recessive trait is observed!

Which DNA fingerprinting technique examines the length variation of DNA repeat sequences in human DNA? variable tandem repeats analysis polymerase chain reaction analysis Y chromosome analysis mitochondrial DNA analysis

Answers

Answer:

mitochondrial DNA analysis

Explanation:

A DNA fingerprint is a laboratory technique that identifies DNA repeat sequences that produce a pattern specific to that individual. Mitochondrial DNA (mtDNA) exhibits several useful features for human identification and for their use in DNA fingerprinting: 1-doesn't undergo recombination, 2-a high copy number, and 3-matrilineal inheritance (i.e., mtDNA is inherited from the mother). It is for these reasons that mtDNA fingerprint analysis has become very useful for human identification.

There are thousands of different
proteins being produced within the
cell. How does a cell 'know' which
proteins to produce?

A. The ribosomes produce the proteins by
communicatiing with the cell.
B. The DNA segments code for different protein
production.
C. All proteins are the same.

Answers

Answer:

I think its A...

Explanation:

Because a cell has to communicate with someone to identify the objects or things that goes inside it.

The ribosomes produce the proteins by communicating with the cell. The correct option is A.

What are ribosomes?

Ribosomes are tiny molecules made up of RNA and related proteins that are responsible for protein synthesis.

Proteins are required for many cellular activities such as emergency repairs and chemical process control.

Ribosomes are found in the cytoplasm or connected to the endoplasmic reticulum.

Ribosomes have two primary functions: message decoding and peptide bond formation.

The ribosomal subunits are two huge ribonucleoprotein particles of variable size that house these two activities.

Each subunit is made up of one or more ribosomal RNAs as well as numerous ribosomal proteins.

Ribosomes communicate with the cell to produce proteins.

Thus, the correct option is A.

1. How does carbon enter the soil?

Answers

Carbon moves from plants and animals to soils. When plants and animals die, their bodies, wood and leaves decays bringing the carbon into the ground.

Answer:

Carbon enters the soil through the decomposition of organic material.

Explanation:

Carbon moves from plants and animals to soils. When plants and animals die, their bodies, wood and leaves decays bringing the carbon into the ground. That’s why when humans burn fossil fuels to power factories, power plants, cars and trucks, most of the carbon quickly enters the atmosphere as carbon dioxide gas.

Put the following statements about a synapse in the correct order.
= Vesicles filled with neurotransmitters move to the end of the axonal terminal
= Neurotransmitters attach to the sodium channels on the dendrite.
= Action Potential reaches the Axonal terminal
= Sodium channels open
= Neurotransmitters are released into the synaptic cleft
= Sodium moves into the Dendrite
= Action potential travels through the dendrite

Answers

Answer:

Action Potential reaches the Axonal terminal

Vesicles filled with neurotransmitters move to the end of the axonal terminal

Neurotransmitters are released into the synaptic cleft

Neurotransmitters attach to the sodium channels on the dendrite.

Sodium channels open

Sodium moves into the Dendrite

Action potential travels through the dendrite

Explanation:

The process of transmission of action potential across a synapse ( a junction between two neurons) begins with the arrival of an action potential from the presynaptic neuron. The steps are given below:

Action Potential reaches the axonal terminal of the presynaptic neuron

Vesicles filled with neurotransmitters move to the end of the axonal terminal of the presynaptic neuron

Neurotransmitters are released into the synaptic cleft

Neurotransmitters attach to the sodium channels on the dendrite of the postsynaptic neuron

Sodium channels open

Sodium moves into the dendrite of the postsynaptic neuron.

Action potential travels through the dendrite towards an effector or another neuron.

Answers

Answer:

Cancer is unchecked cell growth. Mutations in genes can cause cancer by accelerating cell division rates or inhibiting normal controls on the system, such as cell cycle arrest or programmed cell death. As a mass of cancerous cells grows, it can develop into a tumor.

Explanation:

Answer:

Disclaimer: I haven't had a proper science class in ages and I forgot most of the terms. I probably don't have the correct answer that you're looking for, but this is to the best of my ability.

Mutations in cells can cause cancer as it will compete with other cells for energy and space. It will continually multiply/rapidly grow and can't be rid of as its internal system of apoptosis was hindered during the mutation. Mutations can occur due to damages in the DNA.
