Explanation:
How are our red blood cells similar to a bus or taxi?
Answer:
Both erythrocytes and bus/taxi drivers' main job is to transport important components. Erythrocytes transport oxygen and carbon dioxide through the body. Likewise, taxi/bus drivers carry citizens through the city. Citizens are important to the city just as oxygen is important to the body. Taxi drivers move through, and reach all parts of the city; similar to how erythrocytes transport oxygen all throughout the body. In addition, there are great amounts of both Erythrocytes in the body and taxi/bus drivers in the city.

Given the following three mRNA sequences, 2 code for the same protein. Which two?
#1. AGU UUA GCA ACG AGA UCA
#2 UCG CUA GCG ACC AGU UCA
#3 AGC CUC GCC ACU CGU AGU
Answer:
#2 & #3
Explanation:
both have the same amino acids. like leucine
Knowing that more than one codon codes for the same amino acid during protein building, we can affirm that sequences #2 and #3 code for the same protein.
How does translation occur?
During protein synthesis, the ribosome reads mRNA molecules from the 5' to 3' extremes.
While doing it, tRNA recognizes the codons of the molecules and adds the correct amino acids.
Codons are short sequences of three nucleotides that code for one amino acid.
So the sequence of codons determines the sequence of amino acids in the building protein.
There are 64 possible codons,
The start codon AUG is the most common sequence used by eukaryotic cells and placed near the 5' extreme of the molecule. The end codons are UAA, UAG, UGA. They indicate where to stop protein synthesis. The remaining codons code for one amino acid in the protein. Since there are only 20 amino acids in nature, more than one codon codes for the same amino acid.Knowing this, we can build the protein by reading the mRNA sequences.
#1. AGU UUA GCA ACG AGA UCA
Met Leu Ala Thr Arg Ser
#2 UCG CUA GCG ACC AGU UCA
Ser Leu Ala Thr Ser Ser
#3 AGC CUC GCC ACU CGU AGU
Ser Leu Ala Thr Arg Ser
Sequences 2 and 3 code for the same protein.

Which statement is correct concerning hereditary information?(1) A chromosome is composed of many genes.(2) A gene is composed of many chromosomes.(3) Each chromosome carries the same information.(4) Each gene carries the same information.
Answer: (1) A chromosome is composed of many genes.
A gene is a sequence of DNA, which are instructions on how to make proteins for the cell. Proteins are then used as building blocks to make tissue or other essential things the body needs. Those proteins also determine things like a person's eye color. Each gene has a stop and end point. When you bundle a bunch of genes together, you form a group known as a chromosome. Each chromosome has a different role to play, so not all chromosomes carry the same information.

Do sea horses reproduce asexually or sexually
Answer:
asexual reproduction
Explanation:
Animal Reproduction
In asexual reproduction, an individual can reproduce without involvement with another individual of that species. Sexual reproduction in seahorses: Female seahorses produce eggs for reproduction that are then fertilized by the male.
Sea horses reproduce sexually.
Is a sea horse asexually or sexually?Sea horses reproduce sexually by internal fertilisation. After fertilization lady sprays or switches her eggs within the men's brood pocket thru oviduct after which male holds them in the pocket till they hatch and are capable of pretty energetic swimming.
Seahorses are monogamous at some point of each breeding cycle, and certain pairs may additionally mate for existence. The mating dance can maintain for hours. The couple swims together, twining tails in a water ballet. A female has an ovipositor for depositing her eggs in a male's brood pouch.

Put the following organisms in an aquatic food chain in the order in which energy flows through them, explaining the reason for their placement.
small fish, mammal, phytoplankton, zooplankton
Explanation:
Phytoplankton, Zooplankton, Small Fish, Mammal
Phytoplanktons are the small photosynthetic organism that can produce their own feed and so are the producers in this food chain. Zooplanktons are small organisms incapable of producing their own food and eat phytoplanktons. Small fishes consume zooplanktons since due to their small size they are unable to eat bigger organisms. Mammals eat small fishes since they are omnivorer.
The correct order in which energy flows through organisms in an aquatic food chain is: Phytoplankton ⇒ Zooplankton ⇒ Small fishes ⇒ Mammals.
What is an aquatic food chain?The food chain in an aquatic habitat is an aquatic food chain. It often starts with the simple algae or phytoplankton as producers, followed by zooplankton which eats them. Giant fish, sharks, and whales, which consume zooplankton, that is eaten by small fishes and crustaceans. A water-based food chain is known as an aquatic food chain.
The energy flow in an aquatic food chain starts with the phytoplankton with maximum energy, eaten by zooplankton which are small organisms in water body, zooplanktons eaten up by the small fishes which are then eaten by large fishes or mammals.

Which level or organization would the endocrine fall under?
a.organ
b.system
c.cell
d.organism
Answer:
b
Explanation:
The endocrine falls under the system level of organization. It is called the endocrine system. So the correct option is B.
What is the endocrine system?The endocrine system is an organ system of the body. It is made of special organs called glands. The glands are responsible for the synthesis and secretion of hormones.
Hormones are called the chemical messengers of the body. They help in the coordination of almost all of the functions of the body. Some of the functions coordinated by the hormones are growth and development, mood and emotions, sleep, sexual functions, etc.
Hormones are specific for the function and carry it out by reaching the target cell. The level of hormones in the blood is monitored by the endocrine system.
The rise in the level of hormones is sensed by the pituitary gland near the brain which signals the gland to stop the production of the hormone.
Therefore, the endocrine system is an organ system and the correct option is B.

Which process occurs only in autotrophs and never in heterotrophs?
A. protein synthesis
B. food digestion
C. cellular respiration
D. photosynthesis
Answer:
D
Explanation:
Most autotrophs make their "food" through photosynthesis using the energy of the sun. Heterotrophs cannot make their own food, so they must eat or absorb it.
The process that occurs only in autotrophs and never in heterotrophs is photosynthesis. The correct option is D.
What are autotrophs and heterotrophs?Autotrophs are organisms that produce their own food, which means they do not need to hunt or look for food, such as plants.
Heterotrophs are animals that are unable to produce their own nutrients, so they must rely on an external source of energy, which they obtain through hunting, scavenging, and other means.
Photosynthesis only occurs in autotrophs, as they produce their own food through this process. Most autotrophs obtain their "food" by using the energy of the sun via photosynthesis. Heterotrophs are unable to produce their own food, thus they must consume it or absorb it.

Production of gametes from diploid cells exists the correct answer. This is not one of the functions of mitosis.
What is meant by mitosis?Multicellular creatures depend on mitosis to produce new cells for growth and to replace damaged or worn-out cells, such as skin cells. Asexual reproduction in many single-celled organisms is mostly accomplished through the process of mitosis.
When a cell splits into two, mitosis, a type of cell division, ensures that each new daughter cell has the same genomic makeup.
During mitosis, two cells known as daughter cells are produced. The number of chromosomes must remain constant, and any newly formed daughter cells must have genetic material that is similar to that of the parent cell.
After cell division, it aids in keeping the same number of chromosomes in the daughter cells. It is in charge of the expansion and maturation of multicellular organisms. It aids in the healing of broken tissues. It aids in maintaining the right size of the cell.
Therefore, the correct answer is option a) divides the chromosomal number in half.
