Answer:
Around the year 7.1 billion AD, the Sun will begin evolving so rapidly that it will cease to be a main-sequence star. Its position on the H-R diagram will begin to shift from where it is now, near the center, towards the upper right where the red giants live.
When offspring produced by sexual reproduction move into different environments, new species sometimes emerge over time. Which characteristic of sexual reproduction allows this result to occur?
A) speed with which offspring are produced
B) number of offspring produced
C) diversity of the offspring produced
D) size of the offspring produced
Answer:
c) diversity of the offspring produced.
Explanation:
Because sexual reproduction involves gametes (sex cells with only half the number of chromosomes), each offspring produced is genetically unique (as they get a random selection of chromosomes from both parents). This allows mutations to occur, which may be beneficial (or not) in the environment. Over time, the offspring that have the favourable characteristics will survive more easily to reproduce, whereas those with less helpful characteristics will not. This means that the favourable characteristics will be passed on to the next generation, while the less favourable ones will not be time. If this occurs for many generations, a new species may emerge.

Which relationship occurs between prey and another organism? (3 points)
Commensalism
Mutualism
Parasitism
Predation
Answer:
Predation
Explanation:
Answer:
Predation
Explanation:
Predation is the interaction between two organisms in which one organism is harmed which is prey and other organism is benefited who is predator.
In predation, predator kills the prey and consumes it to get energy. Predators by killing their pray control the population of prey in nature and help the ecosystem to remain in a balanced position.
For example, lions hunt deer and eat them. Here lion is the predator and deer is the prey and lions control the overgrowth of deer in the wild by preying in deer. Therefore the correct answer is Predation.
8. Which organisms are responsible for changing atmospheric nitrogen gas to
ammonium and then into nitrate and nitrite?
Answer:
Will this help ??
Explanation:
Nitrogen-fixing bacteria in the soil and within the root nodules of some plants convert nitrogen gas in the atmosphere to ammonia. Nitrifying bacteria convert ammonia to nitrites or nitrates. Ammonia, nitrites, and nitrates are all fixed nitrogen and can be absorbed by plants.

a) Why did some of the komodo dragon's eggs not hatch?
Answer:
most likely they were not fertile.
A molecule has been isolated from a cell. The molecule's structure has a three dimensional shape and is made of folded chains of amino acids. The function of this molecule is enzymatic catalysis of glycolysis. An analysis of this molecule would show that it contains which of these elements that would NOT be found in carbohydrates
Answer:
Nitrogen.
Explanation:
Although the options for this question is not available,the major food molecules of Carbohydrate,Protein ,and Lipids all contain the elements C,H,O.
However,Nitrogen is the only elements that is present in Protein,but absent in the other food molecules.Consequently,Nitrogen is answer.
The Nitrogen forms the Amine-NH2 - of protein.
The fact that the molecular structure has a 3-D shape,with folded chains of amino acids,it show that it is protein of tertiary structure.Although enzymes are globular proteins but of tertiary structure.
Tertiary proteins are 3-D and the R-groups interacts with each other for distinct chemical structure

in the lytic cycle the virus uses a host cell to manufacture more viruses;The viruses then burst out of the cell
Activity
In this activity, you will research the genetic diversity in two fish variants. The Mexican tetra (Astyanax mexicanus) has two notable variations: the surface variety and the blind cave fish variety. In this activity, you’ll use credible websites to find the following information about these two fish:
What type of habitat does each fish live in?
How do their physical characteristics differ?
How are they similar?
Can the two types mate with each other?
Why are their characteristics advantageous to their environments?
When you’ve found the information, answer the following questions.
Part A
What are the similarities and differences between the two fish varieties?
Answer:
The surface fish lives near the surface of the water, but the blind fish live in caves.
Explanation: yes
Answer:
The surface fish live near the surface of the water, and the blind cave fish live in dark subterranean caves. The surface fish have eyes and pigmentation on their bodies. The blind cave fish don’t have eyes, and they’re often albinos.

Which are all the correct products of respiration?(1 point)
water and energy
carbon dioxide, water, and energy
carbon dioxide and water
carbon dioxide, water, and glucose
Answer:
[tex]\boxed {\tt Carbon \ dioxide, \ water, \ and \ energy}[/tex]
Explanation:
Cellular respiration is a process in the mitochondria to produce useable energy. The formula is:
oxygen + glucose ⇒ carbon dioxide + ATP + water
Oxygen and glucose go in to produce carbon dioxide, ATP or energy, and water. Therefore, oxygen and glucose are the reactants and carbon dioxide, energy, and water are the products.
The correct answer is B. carbon dioxide, water, and energy.

After transcription, the new mRNA strand travels to the cytoplasm and over to the ___________ where the genetic code will be translated into amino acids.
nucleus
cell membrane
ribosomes
golgi bodies
After transcription, the new mRNA strand travels to the cytoplasm and over to the RIBOSOMES where the genetic code will be translated into amino acids.
During gene transcription, a specific fragment of DNA called gene is used to produce a complementary messenger RNA (mRNA) sequence in the cell nucleus.
Subsequently, this mRNA travels to the cytoplasm where it is used as a template to synthesize a polypeptide chain in the ribosomes by a process called translation.
Ribosomes are protein factories that read the genetic code in the mRNA sequence (i.e., the codons of the mRNA) to translate it into the correct order of amino acids of the protein.
In conclusion, after transcription, the new mRNA strand travels to the cytoplasm and over to the RIBOSOMES where the genetic code will be translated into amino acids.
