Archaea are prokaryotes.
What are prokaryotes?The simplest form of life on our planet is made up of single celled organisms called prokaryotes that lack any nucleus or membrane bound organelles. Despite their basic structure compared to eukaryotic cells they have extreme significance for our environment as they constitute the majority of life forms on Earth.
Prokaryotes can be broadly divided into two groups: bacteria and archaea. Bacteria outnumbers all other types present globally and flourish across all possible conditions - both regular and adverse including tough terrains like hot springs or acidic lakes; however archaic forms can survive even some brutal conditions such as deep sea zones or within rocks.

Answer:
Altruism occurs when an individual gives to another out of concern or thought of one's well-being. If an individual has no expectation of returning to a restaurant then leaving a generous tip is considered altruistic because there is no expectation of a reward from the server. If the customer does not return, the server is unable to exchange the gift or tip for good service. Therefore, the customer who tips is giving out of care or concern for the well-being of the server rather than giving with the intention of receiving an external reward.
Select the correct answer. Plants, through the process of photosynthesis, use solar energy to produce the end product glucose. Since energy is used here, what type of reaction is photosynthesis? A. Endergonic reaction B. Exergonic reaction C. Reversible reaction
Since energy is used, the type of reaction photosynthesis is : ( A ) Endergonic reaction

If t=talk and t= short what will be the physical appearance of the offspring in the cross
Answer:
If T=tall and t=short, what will be the physical appearance of the offspring in the cross?
Explanation:
It looks like your question is incomplete, so I'll try to fill in the blanks.
The offspring will depend on the parents. Each parent will need two alleles, so each parent would have to be TT (tall), Tt (tall) or tt (short--this is the only way to have a short individual).
Here are all the possible crosses:
TT X TT = 100% TT (all tall)
TT X Tt = 50% TT, 50% Tt (all tall)
TT X tt = 100% Tt (all tall)
Tt X Tt = 25% TT (tall), 50% Tt (tall), 25% tt (short)
tt X tt = 100% tt (short)
Note that if there is a T present in the genotype (TT or Tt), that individual will be tall. The only way to produce short offspring is for the both parents to have a copy of the short allele (t).

Chemical properties of blood and red blood cells allow for efficient transport of gases throughout the body.Carbon dioxide and oxygen are exchanged across capillary and alveolus walls.Hemoglobin binds with and transports oxygen that diffuses from alveoli to capillaries. It also increases the efficiency of gas exchange.Carbon dioxide is transported in the blood in three ways. Most combines with water and forms carbonic acid. Some dissolves in plasma. Some binds to hemoglobin and proteins in plasma.
