Summarize the order of events from egg and sperm to embryo?
(ill give brainliest)
Sperm fertilizes the egg, the egg turns into a zygote, the zygote then goes through the process of cell division and turns into an embryo.
• Post ejaculation, the sperm cells meet the egg, and fusion between both the cells takes place.
• The fusion results in the formation of a single cell, which comprises the genetic material from both the egg cell and the sperm cell, this is called a zygote.
• The zygote further divides into sixteen cells stage called the morula.
• Post three days after the formation of morula, formation of the embryo takes place. The embryo attaches to the wall of the mother's uterus.
Thus, egg and sperm fuse and give rise to the zygote, this zygote further undergoes several divisions and eventually results in the formation of an embryo.

Answer
OPTION B.
because from muscle cell ,muscle tissue arise and then after development of muscle tissues organs are formed.
The parts from least complex to most complex is muscle cell, muscle tissue, stomach. So, the correct option is (B).
What is Digestive System?The human digestive system consists of the gastrointestinal tract with the accessory organs of digestion which involve breaking down food into smaller and smaller components until they can be absorbed and assimilated into the body.
The GI tract consists of series of hollow organs which is joined in a long, twisting tube from the mouth to the anus. The processes of digestion consists of six processes:-
1. Ingestion
2. Propulsion
3. Mechanical or physical digestion
4. Chemical digestion
5. Absorption
6. Defecation.
The complexity of the digestive system involves muscle cell, muscle tissue, stomach and organ system from least complex to most complex.
Thus, the parts from least complex to most complex is muscle cell, muscle tissue, stomach. So, the correct option is (B).

Which of these is the correct amino acid chain produced from the DNA template strand?
Arginine – Leucine - Proline – Asparagine – Lysine – Arginine
Serine - Leucine – Proline – Asparagine – Lysine – Arginine
Tryptophan – Phenylalanine – Leucine – Glycine – Asparagine – Phenylalanine
Tryptophan – Phenylalanine – Leucine – Glycine – Asparagine - Serine
The correct amino acid chain produced from the DNA template strand will be Arginine – Leucine - Proline – Asparagine – Lysine – Arginine. The correct option is A.
What is amino acid?Amino acids are molecules that form proteins when they combine. The building blocks of life are amino acids and proteins.
Amino acids are left over after proteins are digested or broken down. To help the body, the human body uses amino acids to make proteins: Food should be broken down.
A codon is a three-nucleotide (DNA or RNA) sequence that forms a unit of genomic information encoding a specific amino acid or signaling the end of protein synthesis (stop signals).
There are 64 different codons, 61 of which specify amino acids and three of which serve as stop signals.
The amino acid sequence for the given template will be:
3' AGGUUACCGAAUAAACGU 5'
So, as per three letter code, the amino acid chain will be:
Arginine – Leucine - Proline – Asparagine – Lysine – Arginine

clear night sky?
A. February 28
B.March 7
C.March 14
D.March 21
Answer:
Okay so the answer is
C...
On February 21, a student observes that the Moon cannot be seen in the clear night sky. The date when the student is not able to see the Moon again is on March 21. The correct option is D.
What is the moon?The moon is the only natural satellite of the earth. It is white and gray and visible from the earth on nights only. It is the fifth-largest satellite in the solar system.
The moon has different phases seen from the earth because the moon revolves around the sun. The four phases have been named full moon, no moon, C moon, and half moon.
In 28 days, the moon is not visible for one day, then the other day it is visible and C-shaped. The student was seen on February 21.
21 + 27 day means 21 march.
Thus, the correct option is D. March 21.

RNA polymerase is used to add new RNA nucleotides to produce RNA.
RNA polymeraseIt is the enzyme responsible for copying the sequence of DNA into the sequence of RNA during the process of transcription.
The information encoded in DNA is used to produce RNA during the process of transcription.
The production of RNA takes place by the enzyme RNA polymerase, by using the antisense strand of the DNA as the template by supplementing the complementary RNA nucleotides to the 3 prime terminal of the developing strand.
The enzyme RNA polymerase combines with the DNA at a sequence known as the promoter at the time of the beginning of transcription.

Which statement about the relationship between the ocean and atmosphere is MOST accurate? A Ocean currents do not affect the atmosphere. B The atmosphere stores more heat than the ocean. C The ocean can hold heat more efficiently than the air. D Ocean currents can move faster than air or wind currents.
The statement about the relationship between the ocean and atmosphere which is most accurate is that the ocean can hold heat more efficiently than the air and is denoted as option C.
What is Atmosphere?This is referred to as the layer of gases which envelop the planet and the gases which are present include oxygen, nitrogen etc. The atmosphere ensures that there are gases available for different life forms in the planet as they are required for various types of metabolism and activities.
Ocean on the other hand is referred to as an area which has water present and we know that it has a much higher heat capacity than air which is why it is able to hold heat more efficiently even when it undergoes a slight change in temperature as a result of this property.
This is therefore the reason why option C was chosen as the most appropriate choice.

How do Newton’s laws of motion explain why it is important to keep the ice smooth on a hockey rink so that players can pass a puck as quickly as possible?
Smooth ice reduces the inertia of the hockey puck.
Smooth ice increases the force used to accelerate the hockey puck.
Smooth ice reduces the unbalanced forces that would slow the hockey puck.
Smooth ice decreases the reaction force that the ice exerts on the hockey puck.
It is important to keep the ice smooth on a hockey rink because this reduces the unbalanced forces that would slow the hockey puck.
Frictional forcesFrictional forces are opposing forces to the motion of an object on a platform.
In order to be able to pass a puck as quickly as possible on a hockey rink, there should be a minimal frictional force on the ice surface on which the puck moves.
With minimal opposing forces, the puck will move as unhindered as possible and passing as fast as possible would be easy.
