Which type of bacteria live in the roots of legumes?nitrogen-fixing bacteria
pathogenic bacteria
aerobic bacteria
rickettsia

Answers

Answer 1
Answer: nitrogen fixing bacteria called rhizobia
Answer 2
Answer:

Answer:

The correct answer would be nitrogen-fixing bacteria.

Nitrogen-fixing bacteria live in symbiotic relationship in the roots of plants especially leguminous plants such as peanuts, soybean, pulses et cetera.

The symbiotic bacteria live in the root nodules of the plants.

It helps in fixing the atmospheric nitrogen and converts into the forms which can be used by plants.

In return, plants provide the bacteria with shelter and food (glucose).

Example of symbiotic bacteria would be rhizobia

A man with blood type B marries a woman with blood type A . Their first child has blood type 0 . Use a Punnett square to predict what other blood types are possible for their offspring .

Answers

Answer:

They have 1:4 chances of 0, 1:4 cahnces of AB, 1:4 chances of A, 1:4 chances of B

Explanation:

Blood has three types of alleles: A, B, 0 depending on the type of proteins in blood cells. They can have protein A, B, or not having them 0. The dominant allele will be B or A.

All types of blood are A, B, AB (co-dominance) and 0.

We all have two alleles for each gene, one comes from our mother, and one comes from our father.

If both parents are dominant, but they have a recessive child, you have both heterozygote genes to do the Punnett square.

Mother: I(A)i(0)

Father: I(B)i(0)
The punnett square is attached to this.
The other possibilities are AB, BO, and AO. 
All of them have 25%.

Northern lights or auroras can be seen within the _____ sub-layer.

Answers

The answer is Ionosphere. Northern lights or auroras can be seen within the Ionosphere sub-layer. The ionosphere is the layer of the Earth's atmosphere that contains a large amount of ions and free electrons, it is also able to reflect radio waves, it can also conduct electricity.

Northern lights or auroras can be seen within the ionosphere sub-layer.

Which organic molecule has been made to form in water in the laboratory ?

Answers

Answer: Amino acids.

Explanation:

There were an famous experiment made by two biochemists called Stanley Miller and Harold Urey, in the year of 1953. They made it at the University of Chicago, USA.

In this experiment, Stanley Miller and Harold Urey simulated hypothetical conditions that Earth’s early atmosphere had, in order to test the hypothesis that gases (as the methane, carbon dioxide, ammonia, amonia and water vapor) allowed inorganic chemicals to form organic molecules.

 After one week, these scientis found that organic compounds were formed.

Through this experiment the scientists Stanley Miller and Harold Urey obtained that several amino acids were formed (the most abundant was Glycine).

According to their work, they got 13 of the 22 aminoacids that are used to make proteins in living cells.

Q. list of consequences for the loss of cutaneous senses 1. What are the consequences for a loss of ability to process touch information (pressure, texture, vibration)? 2. What are the consequences for a loss of ability to sense temperature? 3. What are the consequences for a loss of ability to sense pain?

Answers

Cutaneous senses are a sensation of external forces and objects through the contact with the body.
1. The consequences for a loss of ability to process touch information could be a loss of pain; inability to feel injuries, cuts, etc; lack of registering pressure.
2. A loss of ability to sense temperature will lead to injury and burns because the body will not sense the temperature change. The natural reaction to reject the stimulation is absent, so the body could not defend itself.
3. A loss of ability to sense pain will cause tissue and organ damage or some unnoticed infections. Someone could harm itself unintentionally because it will not sense the pain. 

Final answer:

Losing cutaneous sensations can have serious consequences, including difficulty in manipulating objects, risk of self-injury from not feeling pain, and potential burns or frostbite from not sensing temperature changes.

Explanation:

The cutaneous senses include pain (nociception), temperature (thermoception), and touch (including pressure, texture, vibration). Loss of these senses may result in severe consequences.

  1. Loss of the ability to process touch information: This would greatly affect our ability to perceive our environment and engage with it effectively. Without the ability to sense touch, it would be hard to grasp and manipulate objects, leading to difficulty in performing daily tasks. Additionally, it would also put individuals at risk of injuring themselves without realizing it.
  2. Loss of the ability to sense temperature: This may lead to unintentional burns or frostbite as the body wouldn’t be able to detect and respond to extremes of heat or cold.
  3. Loss of the ability to sense pain: Pain serves as a warning signal that something is wrong in our body. Without this sensation, an individual might not know they're hurt and therefore not seek treatment, potentially leading to severe consequences.

Joe, a hiker, stands at the top of a hill on a trail above the ocean. Joe's friend Dave is just starting out at the trailhead, which is at the beach.Which statements about Joe and Dave are accurate? Select three options.

Joe is at a higher altitude than if he was at the beach.
The air Joe is breathing is less dense than the air at sea level.
The air pressure is higher where Joe is than where Dave is.
If Joe keeps going up, air pressure will continue to decrease.
The air Joe is breathing is denser than the air Dave is breathing.

Answers

Answer:

Joe is at a higher altitude than if he was at the beach.

The air Joe is breathing is less dense than the air at sea level.

If Joe keeps going up, air pressure will continue to decrease.

Explanation:

Joe stands at the top of a hill on a trail above the ocean which represents a higher altitude when compared to the beach level.

At higher altitudes the air is usually less dense.

As altitude increases the air pressure decreases.

Answer:

Its C
