Answers

Answer 1
Answer: The prokaryotic cell does not have a nucleus but instead they have a chromosome.
Answer 2
Answer:

Answer:

Prokaryotes are uni-cellular

Explanation:

Meaning they do not have more than one cell, for example; bacteria are prokaryotes.

If the DNA sequence TTCACG is transcribed to AAGGC, what type of mutation has occurred?a. Insertion
b. Substitution
c. Translocation
d. Deletion

Answers

The answer is d. deletion.

If the DNA sequence is TTCACG, it is expected to be transcribed into AAGUGC.
But, it was transcribed into AAGGC. If we count nucleobases, a transcribed sequence has 5 nucleobases, while DNA sequence has 6 nucleobases. These means that deletion happened.
If insertion occurred, there will be 7 nucleobases in transcribed sequence. In substitution or translocation, the transcribed sequence will be the same size, but with different sequence than the DNA sequence.

in order to use the Hardy-Weinberg equation to calculate genetic variations in a population which of the following conditions must exist in the population

Answers

Answer: All organisms must reproduce.

Explanation: Trust me G

APEX. Just trying to help people out who also have this question.

Population of living creatures or living organisms.

Because what can reproduce is a living creature/organism.

Further explanation

The Hardy-Weinberg Principle states that alleles and genotype frequencies in a population will remain constant from generation to generation without any other evolutionary influence. These influences include perfect pairing, mutation, selection, genetic drift, gene flow, and Meiosis steering.

The seven assumptions underlying the Hardy-Weinberg equation are as follows:

  • Such organisms are diploid
  • only reproduce sexually
  • generation that does not overlap
  • random marriage
  • infinite population size
  • same frequency alleles in both sexes
  • no migration, mutation or selection

Which is an example of a behavioral adaptation for a mouse?A.A mouse has sharp teeth that allow it to gnaw through barriers.

B.A mouse has brown fur that allows it to blend into its surroundings and evade predators.

C.A mouse has a keen sense of smell that allows it to find food.

D.A mouse lies still when it sees a cat, which helps it evade detection by a predator.

Answers

The answer is D.A mouse lies still when it sees a cat, which helps it evade detection by a predator.

Behavioral adaptations are thing organisms do to increase their chance to survive and reproduce. This is, actually, how organisms react in response to a threat. For example, animals could move from place to place, or imitate something they are not (mimicry). The example of mouse's behavioral adaptation is when mouse sees a cat, it lies still in order to evade it. Mouse changes its behavior to survive.

Rising levels of carbon dioxide most likely

Answers

Answer:

The elevating levels of carbon dioxide most probably can diminish the productivity on the land and the sea. In case, when there is an elevating level of carbon dioxide in the atmosphere, more amount of carbon dioxide gets dissolved within the water bodies like sea. This further enhances the levels of pH, which leads to coral bleaching and other deleterious things that can hamper biodiversity found in the water ecosystem.  

Even on land, the phenomenon of global warming resulting due to an increase in the levels of greenhouse gases leads to change in climate. Due to change in climate, a decline can be witnessed in the diversity of crops, and thus also diminishes productivity, which hampers farmers that depends on productivity as the source of income.  
Since the Inbdustrial Revolution, human sources of CO2 emissions have been growing.
Activities such as buring fossil fuels, and deforrestation are the primary cause of the increased CO2 concentrations in the atmosphere.

The roots of the aquatic plant hydrilla are poorly developed and lack xylem tissue. Which is an appropriate justification for this? 1.As hydrilla is aquatic in nature, the roots do not have to search for oxygen, and there is no need for xylem to absorb oxygen because the plant is surrounded by water that has dissolved oxygen in it. 2.As hydrilla is aquatic in nature, the roots do not have to search for minerals,and there is no need for xylem to absorb nutrients because the plant is surrounded by water that has dissolved nutrients in it 3.As hydrilla is aquatic in nature, the roots do not have to search for water, and there is no need for xylem to absorb water because the plant is surrounded by water.
