Answer:
40kg
Explanation:
F=M*A
M=F\A
M=400\10
M=40kg
The mass of an object whose weight is 400 N and acceleration due to gravity is 10 m/s2 is 40 kg.
What is acceleration due to gravity?The net acceleration that objects get as a result of the combined action of gravity and centrifugal force is known as the Earth's gravity, or g.
It is a vector quantity whose direction, strength, or magnitude match a plumb bob.
According to Newton's second law, an object's acceleration is inversely proportional to its mass and directly connected to the net force. An object's acceleration is determined by two factors: force and mass.
We know that,
F = m x g
m = f/g
Where,
F = force
m = mass
g = acceleration due to gravity
Given that,
F = 400N.
g = [tex]10m/s^2[/tex]
So,
m = 400/10
m = 40 kg.
Thus, the mass is 40 kg.

In pea plants, the allele that produces purple flowers (P) is dominant to the allele that produces white flowers (p), and the allele that produces tall plants (T) is dominant to the allele that produces short plants (t). Two pea plants are crossed and produce 521 offspring, and the results of this cross are shown below:
Phenotype Number of offspring
Tall with purple flowers 291
Short with purple flowers 97
Tall with white flowers 101
Short with white flowers 32
Which cross would MOST LIKELY lead to this outcome?
Pptt × ppTt
pptt × PPTT
PpTt × PpTt
ppTT × PpTt
Answer: PpTt x PpTt
Explanation:
The cross PpTt × PpTt leads to the phenotype Number of offspring Tall with purple flowers 291 Short with purple flowers 97 Tall with white flowers 101 Short with white flowers 32, hence option C is correct.
What is a dihybrid cross?Two creatures that are identically hybrid for two characteristics are said to have mated to create a dihybrid cross. When an organism is heterozygous, it signifies that there are two distinct alleles present at a certain genetic location.
An attempt in producing two creatures that are identical hybrids for two qualities is a dihybrid cross.
The people with this sort of character are homozygous for that particular trait.
Therefore, to put it another way, a dihybrid cross is a union of two organisms that are heterozygous for two separate features, hence option C is correct.

If the food on the island is small seeds, what finch is best adapted? Explain why
Answer:Adaptation in Darwins Finches. Beak depth, which is correlated with body size and the ability to crack larger seeds, varies according to drought conditions: plants produce fewer, harder seeds in dry years and more, softer seeds in wet years. Only larger birds with deeper depths survive in drought years.

The division of the cytoplasm, which follows Mitosis, is called...
Answer:
Cytokinesis,
Explanation:
Cytokinesis, the division of the cytoplasm to form two new cells, overlaps with the final stages of mitosis. It may start in either anaphase or telophase, depending on the cell, and finishes shortly after telophase.
The division of the cytoplasm, which follows Mitosis, is called Cytokinesis. This is further explained below.
What is Mitosis?Generally, Mitosis is simply defined as a kind of cell division that produces two daughter cells with the same number and type of chromosomes as the parent nucleus, as seen in normal tissue growth.
In conclusion, Cytokinesis is simply defined as the division of the cytoplasm that occurs after mitosis to produce two daughter cells.

What size molecules can pass through a cell membrane by a process called passive transport?
Answer:
diffusion and osmosis
Explanation:
lipid_ soluble substance
through lipid baleyer
through protein channel
Transported proteins carry small substances like water, amino acids, and charged ions. One to fifteen angstroms is the range in molecule size that can pass through the membrane. The easier it is for a molecule to move across the cell membrane, the smaller it is.
What is cell membrane ?All cells have a cell membrane, also known as a plasma membrane, which separates the interior of the cell from the external environment. A semipermeable lipid bilayer makes up the cell membrane. The movement of materials into and out of the cell is controlled by the cell membrane.
Small molecules or ions can traverse the cell membrane passively without the cell providing any energy. The three basic types of passive transport are osmosis, assisted diffusion, and diffusion.
Gases like oxygen and carbon dioxide, as well as small hydrophobic compounds, quickly traverse membranes. Water and ethanol are examples of small polar molecules that can move across membranes, though more slowly.
Thus, The easier it is for a molecule to move across the cell membrane, the smaller it is.

Why must an mRNA copy be made for Protein Synthesis?
A. Ribosomes cannot read DNA, only RNA.
B. DNA must stay inside the nucleus.
C. Ribosomes are too big to enter the nucleus.
D. DNA is too degenerate to use without mRNA.
Answer:
A
Explanation:
its not D or C and B might be true but its A okay
Why must an mRNA copy be made for Protein Synthesis because C. Ribosomes are too big to enter the nucleus
Why is mRNA important for protein synthesis?
mRNA is the molecule that includes the message contained within DNA to the ribosome. Ribosomes are where proteins are produced. mRNA is vital because ribosomes cannot attain the DNA inside our cell nucleus, which is the region within the mobile wherein DNA is housed.
Why is it important to make an mRNA reproduction of a DNA gene earlier than protein synthesis?
So as for cellular to fabricate these proteins, particular genes inside its DNA should first be transcribed into molecules of mRNA; then, these transcripts must be translated into chains of amino acids, which later fold into completely useful proteins.

When the northern hemisphere points toward the sun, the southern hemisphere faces away from the sun. In this instance, it is:
A.
summer in North America, and winter in Australia.
B.
summer in North America and Australia.
C.
winter in North America, and summer in Australia.
Answer:
A
Explanation:
the northern hemisphere is the opposite from the southern hemisphere
Since northern and southern hemisphere are in opposite directions therefore, option (A) is correct.
Why are the seasons reversed in each hemisphere?The axis of rotation of the Earth is inclined with regard to the plane in which it orbits the sun. This is the root reason of the changing of the seasons. When the axis of the earth is aligned with the sun, summer arrives in that hemisphere of the planet. Expect winter to arrive when the axis of the earth is tilted away from the sun.
Different places of Earth receive the Sun's most direct rays throughout the year. When the North Pole tilts toward the Sun, it's summer in the Northern Hemisphere. When the South Pole tilts toward the Sun, the Northern Hemisphere experiences winter.

1. Describe how the rotation of Earth on its axis affects the tides. Be sure to include the evidence that supports your answer.
Answer/Explanation:
During low elevated tides, the Earth itself is pulled marginally toward the moon, making elevated tides on the contrary side of the planet. Earths pivot and the gravitational draw of the sun and moon make tides on our planet. As the sea swells toward the moon, an elevated tide is made.
But because the Earth rotates, circulating air is deflected. Instead of circulating in a straight pattern, the air deflects toward the right in the Northern Hemisphere and toward the left in the Southern Hemisphere, resulting in curved paths. This deflection is called the Coriolis effect.
