On a field trip, a student in a marine biology class collects an organism that has differentiated organs, cell walls of cellulos

e, and chloroplasts with chlorophyll a. Based on this description, the organism could be a brown alga, a red alga, a green alga, a charophyte recently washed into the ocean from a freshwater or brackish water source, or a land plant washed into the ocean. The presence of which of the following features would definitively identify this organism as a land plant?A) alternation of generationsB) sporopolleninC) rosette cellulose-synthesizing complexesD) flagellated spermE) embryos

Answer:

The answwer is letter E.

Explanation:

Embryos.  Because land plants evolved from aquatic green algae. The transition was easy because of the amount of traits  that allowed the survival of the specie. One of these traits was the embryo, which is so essential that every land plants are known as embryophytes.

Why can’t nucleic acids be formed by sugars alone?
Fofino [41]

Answer:

Nucleic acids

Deoxyribonucleic acid (DNA) and ribonucleic acid (RNA) are made up of nucleic acids found in the nuclei of living cells. They are the vehicles of genetic inheritance.

Nucleic acids are condensation polymers of nucleotides. To understand their functions you will find it helpful to look at how their molecules are built up and the structures of these molecules.

A stream of water holds thriving bacteria. If drought conditions caused the stream to dry up, how would the bacteria mostly like
Alexeev081 [22]

The answer is they produce endospores.

Explanation:

The endospores are dormant, non-reproductive, tough bacterial spores that ensure the survival of bacteria in adverse conditions.

During the environmental stress, such as starvation, desiccation, radiation and chemical treatment many bacteria form dormant endospores. These endospores germinate again when the conditions become favorable.

Hence, if drought conditions lead the stream to dry up, the bacteria that live there would produce endospores to survive.

In the Gizmo, what light intensity and CO2 level do you think will maximize the rate of photosynthesis?Experiment: Use the Gizmo
adoni [48]

Solution :

In Gizmo experiment, when both the intensity of light and carbon dioxide level is high, the rate of photosynthesis will maximize.

A). If the temperature is too hot or cold, it becomes difficult to find the ideal intensity of light because if the temperature is hot, the light intensity will be too high and thus the chlorophyll will get damaged. While if it too low, then it will be difficult for the proper functioning of the cells. And hence the photosynthesis will not take place.

B). It will be considered as a limiting factor if the light intensity is low. With light intensity being low, it will be difficult for the plant for survival and ideal carbon dioxide level will have no role. This amount of carbon dioxide does not help the plant to survive as the light intensity is now a rate limiting factor.

3. In what possible scenario would the female birds evolve to having the singing trait? (5 points)
Iteru [2.4K]

The possible scenario for singing traits in female birds will be about 26% in Generation 4 species

Explanation:

Singing trait have been common among both male and female birds and it is an ancestral traits. However, singing has been more sex-specific with male birds. Reasons for which birds generally sing are:

  • To attract the mates
  • While making nests and laying eggs
  • For the young birds to recognize their parents

However, various studies prove that the singing trait in female birds is reducing with increase in non-singing female birds over the years due to evolutionary course.

Natalka [10]
<span>According to the ipat model, technology that enhances our acquisition of minerals, fossil fuels, timber, and ocean fish increase environmental impact.
IPAT is a model or equation which expresses that 
I (stands for Environmental impact) is the product of three factors: P (stands for population), A (is affluence) and T ( for Technology). 
IPAT can be written as  (I=PAT) or I = pxAxT</span>
