How many chromosomes are in the cells after they divide? How many chromatids are there?
Answer:
two chromatids
After DNA replication, each chromosome now consists of two physically attached sister chromatids. After chromosome condensation, the chromosomes condense to form compact structures (still made up of two chromatids). As a cell prepares to divide, it must make a copy of each of its chromosomes.

The weight of astronaut on the moon will be
A) Less because the moon has less mass
B) Less because the moon has more mass
C) More because the moon has less mass
D) More because the moon has more mass
Answer:
A
Explanation:
The gravity of a body increases with its size. The moon is smaller than the Earth, so an astronaut will weigh less on the moon than they will on Earth. Good luck ^^

Explain how a school bus uses all of these energy types.
-Mechanical
-Chemical
-Electrical
-Thermal
Answer:
Mechanical
94 percent of all school buses in America are powered by diesel engines because of their reliability, durability and safety. Almost half of these (46 percent) rely on the cleanest, near-zero emission diesel engine technology.
Chemical
school bus uses petroleum as chemical potential energy.
Electrical
An electric bus draws electricity from the power grid and stores it in a battery that can be recharged once the electricity has been used up. This basically mirrors the way our electronics work. We plug them in and let the battery charge and then use them wirelessly until it's time to charge again
Thermal
They heat the cold coolant from engine's block to 160° F in as little as one hour, then pump it back to the vehicle's engine and heat exchangers. The result: engine is preheated and the vehicle's heat exchangers distribute an abundance of heat to the vehicle's interior.
How does acid rain (deposition) form and travel to effect the environment?
Answer:
The ecological effects of acid rain are most clearly seen in aquatic environments, such as streams, lakes, and marshes where it can be harmful to fish and other wildlife. As it flows through the soil, acidic rain water can leach aluminum from soil clay particles and then flow into streams and lakes.
Explanation:
What is the purpose of rRNA?
A. to retrieve amino acids
B. to be a working copy of DNA
C. to assemble proteins
D. to replicate the genetic code in mitosis
Answer:
A
Explanation:
The primary function of rRNA is in protein synthesis – in binding to messenger RNA and transfer RNA to ensure that the codon sequence of the mRNA is translated accurately into amino acid sequence in proteins.
In a sample of double stranded dna if 27% of the nitrogenous bases are thymine what percentage of nitrogenous bases are cytosine
Answer:
23%
Explanation:
According to Chargaff's law A = T and G = C
T = 27%
A = 27%
27 + 27 = 54
100 - 54 = 46
46/2= 23
So 23%
What structure is found in viruses but not in cells
Answer:
Acellular
Explanation:
Viruses are acellular, meaning they are biological entities that do not have a cellular structure. Therefore, they lack most of the components of cells, such as organelles, ribosomes, and the plasma membrane.

Please Help I will mark bRAINLIEST
Answer:
d
Explanation:
In particular, organelles called chloroplasts allow plants to capture the energy of the Sun in energy-rich molecules; cell walls allow plants to have rigid structures as varied as wood trunks and supple leaves; and vacuoles allow plant cells to change size.

Why would the location of resources be a concern?
A) Some areas have more access to resources than others.
B) Human populations are sometimes concentrated in areas that are lacking resources.
C) Areas with fewer resources may need to buy resources from other areas.
D) All of the above
Answer:
D is the correct option
Explanation:
why???
let's see option by option
A)if an area is having a resource then the people around it or near it will access it more which can lead to end of the resource.so there should be rule to use equal resource by everyone
B) sometimes when there is a drought or phenomena in living area so people living there might face issues with the resources they had and now they are gone.so right thing is to move from that place to ankther place where there is resources
C)in areas that are near to desert or hilly areas might not have enough resources near them. so that may cause people to spent money to bring that resources near them or energy waste will be there.so in that cases they should either renovate that place for living or not to live there.

The fact that choanoflagellates and collar cells of sponges resemble each other supports the inference that ________. Group of answer choices choanoflagellates are animals choanoflagellates are more closely related to sponges than they are to protists choanoflagellates and sponges evolved similar cell structures through convergent evolution choanoflagellates and sponges are sister groups
Answer:
choanoflagellates and sponges are sister groups
Explanation:
The choanoflagellates are small unicellular organisms belonging to the Protista kingdom. These microorganisms are collared flagellates morphologically similar to the choanocyte cells of animal sponges, which have a central flagellum surrounded by a collar of microvilli. In consequence, it has been suggested that choanoflagellates may represent the closest living relatives of primitive metazoans (i.e., they are sister groups to sponges). This hypothesis has recently been supported by both molecular phylogenetic and comparative genomic analyses.

Describe the Lysogenic cycle.
No dam links
Answer:
Here ya go
Explanation:
The lysogenic cycle, is one of two cycles of viral reproduction. Lysogeny is characterized by integration of the bacteriophage nucleic acid into the host bacterium's genome or formation of a circular replicon in the bacterial cytoplasm. In some interactions between lysogenic phages and bacteria, the lysogenic conversion may occur, which can also be called phage conversion.
