Answer:
a. miniscule
Explanation:
A microorganism that is smaller than a bacterium that cannot grow or reproduce apart from a living cell.
Viruses are really small, much smaller than cells described as miniscule. Therefore, the correct option is A.
They are so small – ranging from 20 to 300 nanometers in size – that they can only be seen under an electron microscope. These infectious organisms are composed of genetic material, either DNA or RNA, that is coated with an inhibitory protein. Their ability to invade host cells and control the cellular replication machinery increases their pathogenicity.
Many diseases can be brought on by viruses, including the common cold, influenza, COVID-19, and more serious infections. To create vaccinations, antiviral drugs, and public health measures to prevent outbreaks and protect world health, it is essential to understand how viruses work. The complexity of these small but powerful agents is still being uncovered by ongoing research.

In what way is binary fission different from mitosis?
Binary fission is asexual reproduction where singled cell organisms copies of themselves. Mitosis is cell division that a cell and results in two newly formed cells that are identical. Binary fission is making copies of a cell, and mitosis is splitting a cell into two new indetical new ones.
Answer:
Explanation:
Mitosis is a type of cell division that takes place among non-sex cells (somatic cells). This type of cell replication is designed to increase the number of cells during the blastogenesis and embryogenesis of both animals and plants. The most distinct characteristic of the mitotic process is the production of two product cells (daughters) which are similar to each other as well as to their original cell (mother) in both quantitative and qualitative aspects
Binary fission has three types: simple, transverse, and longitudinal binary fission. Simple binary fission happens in amoebas wherein the division goes by any plane. Transverse binary fission happens among paramecium and planaria wherein the cytoplasmic division plane matches the specimen’s transverse axis. Longitudinal binary fission occurs in the euglena when the plane matches the longitudinal alignment.

Which of the following is an example of homeostasis?
Humans shiver when it is very cold.
We cover ourselves with a blanket when it is cold.
We take a shower to keep the body temperature low.
An air conditioner keeps the body at a normal temperature.
i think its A, B, or C
Answer:
Humans shiver when it is very cold.
Explanation:
"Homeostasis" is the ability of the body to regulate itself in order to maintain a steady state. This includes mechanisms that allow automatic adjustment when the need for it arises. Covering ourselves with a blanket, taking a shower and turning on the air-conditioner are "not self-regulated" activities because they are done "intentionally" by the person. It is only "shivering" that shows the body's regulation of heat.
When the environment is cold, the skeletal muscles of the body respond by rapidly contracting and relaxing. This is what you call as "shivering." It produces heat through "respiration." Thus, it helps increase the body temperature.

What response would likely occur in an animal if the environmental temperature increased?
O blinking
O grouping
o shedding
CAN
shivering
Answer:
shedding
Explanation:
they would lose hair/fur allowing more waste heat to be lost into the environment so that the body could be cooler.
If the environmental temperature increases, the animal is most likely to shed, which is present in the third option because shedding the fur that is present on the skin is helpful for the relief of the heat.
What is the significance of the heat in the animal body?Heat regulates the internal temperature, organ activity, blood pH, and a variety of other functions in the animal body. Animals living in colder climates have more hair and fat than those living in warmer climates, which is due to their need to protect their internal body temperatures. In the case of colder weather, the skin or the fur acts as an insulator and protects the animal by conserving the heat, while in a hot climate, the animals shed these in order to release the heat.
Hence, as the environmental temperature increases, the animal is most likely to shed, which is present in the third option.

Susan and Michael travel on separate trains. Susan's train moves westward at a constant speed of 5 meters per second. Michael's train
moves eastward at a constant speed of 7 meters per second. How fast is Susan's train moving relative to Michael's train?
Answer:
[tex]V =2m/s[/tex]
Explanation:
Given:
Represent
- Susan's velocity with [tex]V_s[/tex]
- Michael's velocity with [tex]V_m[/tex]
[tex]V_m = 7m/s[/tex] eastwards
[tex]V_s = 5m/s[/tex] westwards
Required
Determine how fast is [tex]V_s[/tex] relative to [tex]V_m[/tex]
From the question, one train moves eastwards while the other moves westwards.
This means that travel in opposite travel and the relative speed (V) is calculated as:
[tex]V = V_m - V_s[/tex]
Substitute values for [tex]V_s[/tex] and [tex]V_m[/tex]
[tex]V =7m/s - 5m/s[/tex]
[tex]V =2m/s[/tex]
Hence, the Susan's train is moving 2m/s in relative to Michael's train

Explanation:
Gravity is the force that gives weight to objects and causes them to fall to the ground when dropped. Two major factors, mass and distance, affect the strength of gravitational force on an object. You witness the first factor in everyday life - more massive objects are heavier.
Answer:
Gravity is the force that gives weight to objects and causes them to fall to the ground when dropped. Two major factors, mass and distance, affect the strength of gravitational force on an object. You witness the first factor in everyday life - more massive objects are heavier.
Explanation:
"Acceleration due to gravity" typically refers to the increase in speed of a falling object due to the gravitational pull of the Earth. If jump out of a plane, your speed increases towards the Earth (or the center of the Earth really) due to the acceleration of gravity. If you throw a ball up in the air, it slows down and falls due to the acceleration of gravity. I guess it's specified because the force of gravity is causing the acceleration in these instances; as opposed to some other outside force.
In dragons, green scales are dominant to brown scales. A mating between a dragon with green scales and a dragon with brown scales produces offspring with a speckled pattern of green and brown scales. What are the genotypes of the two parents and the offspring?
Answer:
The correct answer would be -
parent 1: GG
parent 2: gg
offspring: Gg
Explanation:
Let assume the dominant allele of the dragon scale is represent by G and the recessive allele that expressed in brown is represented by g. As it is given that offspring by mating is expressing this trait as a speckled pattern of both alleles brown and green which means it shows codominance where both alleles expressed together in offspring if present in heterozygous condition.
So, the cross between GG and gg will result in a heterozygous combination to produce offspring with a speckled pattern of brown and green scales.
The correct answer would be -
parent 1: GG
parent 2: gg
offspring: Gg
