Answer:
The hypothesis that eukaryotic cells evolved from a symbiotic association of prokaryotes (endosymbiosis) is particularly well supported by studies of mitochondria and chloroplasts, which are thought to have evolved from bacteria living in large cells.
Explanation:
Both mitochondria and chloroplasts are similar to bacteria in size, and like bacteria, they reproduce by dividing in two.
Genetically modified (GM) crops are foods that have had their genomes modified, allowing humans to increase the production of certain crops. Farmer A purchases GM seeds that are immune to a specific herbicide. She plants these seeds in rows over seventeen acres. The following spring, Farmer A's neighbor, Farmer B, tells her that nearly a third of the plants in his crop fields have the same immunity.
Which of the following describes the most likely explanation for this occurrence?
a.Rabbits which frequent both fields carried the seeds across to Farmer B's land.
b.Farmer A's crops cross-pollinated with Farmer B's crops on the neighboring land.
c.The two farms share an irrigation system which transmitted the immunity from one field to another.
d.By increasing the genetic diversity in Farmer A's crops, they have out-competed the crops on Farmer B's land.
Answer:
B.Farmer A's crops cross-pollinated with Farmer B's crops on the neighboring land.
Explanation:
Herbicide resistant genes may transferred to from Farmer A's plants to farmer B's plants via pollination. Option B is correct.
Jumping Gene:
It is a concept in biology which says that the genes present in the one plant can transfer to another plant via pollination. They are also known as Transportable elements.
Here Herbicide resistant genes transferred to from Farmer A's plants to farmer B's plants.
Therefore, Herbicide resistant genes may transferred to from Farmer A's plants to farmer B's plants via pollination.

According to this phylogenetic tree, which of the following pairs of organisms is the most closely related?
A Sharks and ray-finned fishes
B Amphibians and primates
C Primates and rodents/rabbits
D Rodents/rabbits and birds
According to this phylogenetic tree, which of the following pairs of organisms is the most closely related?
Answer:C. Primates and rodents/rabbits
#CARRYONLEARNING #STUDYWELLBy looking at the phylogenetic tree, we can tell which taxonomic groups are more closely related to each other or less related. In this phylogenetic tree, primates and rodents/rabbits is the pair most closely related.
---------------------------------------------------------------
The phylogenetic tree is composed of,
Lineages → The taxonomic groups of interest. These are placed in the extremes of the branches. Nodes → These are the ramification points, which are also known as divergence points. They represent the location of the most recent common ancestor. Root → This is the older common ancestor that all lineages share. The first one in the tree.⇒ Highly related groups that share a recent common ancestor. This means that they all diverge from the same node.
⇒ Lineages less related to each other are those whose common ancestor is far away in history.
In the exposed pylogenetic tree, there are two groups of linages that are closely related to each other.
Group 1 ⇒ Primates and rodents/rabbitsGroup 2 ⇒ Reptiles and birdsThese two groups share a common ancestor farther away, which is the point from where each group diverge.
Among the given options, we have
A) Sharks and ray-finned fishes ⇒ Not closely related
B) Amphibians and primates ⇒ Not closely related
C) Primates and rodents/rabbits ⇒ CLOSELY RELATED
D) Rodents/rabbits and birds ⇒ Not closely related

What is the greenhouse effect?
Answer:
the trapping of the sun's warmth in a planet's lower atmosphere, due to the greater transparency of the atmosphere to visible radiation from the sun than to infrared radiation emitted from the planet's surface.
Explanation:
Answer:
It keeps plants warm and gives it the right amount of sun and warmth it needs and it doesn't get to much water from rain because you can choose the amount of water you provide as long as you give it enough to live in a hot area such as a greenhouse.
_____ is used to find the gene that codes for a protein by matching amino acid sequences to codons, mRNA to cDNA, and cDNA to natural DNA.
Answer:
mRNA
Explanation:
This is because mRNA is a single stranded RNA molecule which is produced from the process of transcription and it's compliment one of the strand of DNA gene. They are made in the nucleus and later moved to the cell cytoplasm where translation occur. The RNA molecule is decided by RIBOSOMES during protein synthesis and it match amino acids to codons.
Cellular respiration is called an aerobic process because it requires _______________.
Answer:
Cellular respiration is called an aerobic process because it requires oxygen and carbon dioxide.
Explanation:
Cellular respiration is the process through which cells convert sugars into energy. The energy comes from the fuel molecules such as Glucose(sugar) or Lipids(fats). In cellular respiration, Glucose molecule is dismantled in the presence of oxygen. The bonds between the glucose break forming a simpler molecule and energy is released in small amounts. Some of the energy is stored by cell in the form of ATP while rest is lost as heat. So, ATP is formed from glucose through endergonic and exergonic reactions. The aerobic breakdown of glucose molecule accompanying synthesis of ATP is called celluar respiration. Carbon dioxide and water are produced as by-products.

Over a 24-hour period, which factor would have the LEAST effect upon the rate of photosynthesis in a geranium plant
Answer:
This question lacks options, the options are:
A. Concentration of carbon dioxide in the air
B. Quality of nitrates in the soil
C. Wavelengths of light
D. Availability of water in the soil
The answer is B
Explanation:
Photosynthesis is the process whereby cells of autotrophic organisms manufacture their food in the presence of sunlight. The rate at which the process of photosynthesis occurs, however, is dependent upon certain factors including the concentration of reactants (water and carbon dioxide), availability of light source etc.
Among the options, the concentration/availability of light, carbon dioxide and water, which are key reactants of photosynthesis, will have greater effect on the rate at which the process occurs than the availability of nutrients (nitrates) in the soil. Hence, the quality of nitrates in the soil will have the LEAST effect upon the rate of photosynthesis in a geranium plant.
Photosynthesis is defined as the process of making food in the presence of sunlight, carbon dioxide, and chlorophyll. It is carried out by algae and plants.
The correct options are:
Option B. Quality of nitrates in the soil
The rate of photosynthesis is highly dependent on the light, concentration of carbon dioxide, and water.
These are the key reactants of photosynthesis, which help the plant prepare food and release oxygen.
The quality of the nitrated in the soil will have the least effect on the rate of photosynthesis of the germanium plant.
Therefore, the correct answer is the quality of nitrate in the soil.

Which statement explains the difference in chromosomes in fruit fly (2n=4)?
O Diploid cells have 2 chromosomes and haploid cells have 4 chromosomes.
O Fruit fly gametes have 2 chromosomes while parent cells have 4 chromosomes.
O Male gametes have 2 chromosomes and female gametes have 4 chromosomes.
O Some fruit fly parent cells have 2 chromosomes and others have 4 chromosomes.
Answer:
O Fruit fly gametes have 2 chromosomes while parent cells have 4 chromosomes.
Explanation:
The fruit fly is a diploid (2n) species with a chromosome number equal to 4, which means that somatic cells have two sets of homologous chromosomes, each set composed of two chromosomes (2n = 4). Moreover, fly gametes are haploid (n) cells, containing each a complete set of two non-homologous chromosomes (i.e., half the amount of DNA compared to parent cells). During meiosis, a single cell divides twice following one complete round of DNA replication, producing thus four gametes with a haploid number of chromosomes.
