4. Which is a factor that keeps Earth in orbit around
the Sun?
A. the gravitational pull of the Sun
B. the orbital path of the moon
C. the continuous motion of the universe
D. Earth's changing speed and direction
Answer: A. the gravitational pull of the Sun
The sun is providing a centripetal force pulling the earth inward toward the sun. At the same time, the inertia of the earth is making it want to move forward in a straight line. The two forces work together to create the net effect of the earth orbiting around the sun. Other planets, moons, asteroids, and celestial objects exert gravitational forces on the earth as well, but nowhere near the amount of what the sun does.
The earth revolves ____ around the sun each year when viewed from above the North Pole

The flame of many stove burners is blue, but the wires of a toaster glow orange. How do you think the temperatures of these two cooking appliances compare?
Answer:
the hotter is it, the more bluish it is. And the more reddish it is, the colder it is
just like the bluer the star, the hotter it is, the redder the star, the colder it is.
Comparing the temperatures of the two cooking appliances ; The temperature emitted in stove burners are hotter than the temperatures emitted by the toaster
White-Blue flames are the hottest flames when combined together but the hottest single flame is the blue flame burning between ( 2,600º F and 3,000º F). Blue flames have more oxygen than other types of flames, hence they burn hottest and this is because gases when burnt are hotter than other materials. while
The orange flame of a toaster burns at a temperature between ( 1100°C to 1200°C) . releasing carbon monoxide as it burns.
Hence we can conclude that The temperature emitted in stove burners are hotter than the temperatures emitted by the wires of a toaster.

Answer:
C. Proprioceptors
Explanation:
Firstly option A. Photoreceptors - Is responsible for our vision and is a subcategory for option D. Exteroceptors.
External receptors that respond to stimuli from outside the body are called exteroceptors.
Option C. is the correct answer because Proprioceptors is the sense of self-movement and body position. It sometimes may also be referred to as our sixth sense.

Answer:
c. All cells are identical
Explanation:
The three statements are all living things are composed of cells, that cells are the basic units of structure and function in living things, and that new cells are produced from existing cells.
And not all cells are identical as there are different types of cells in the human body and there are different organisms.

C. The formation of sea ice removes freshwater and dissolved solids from seawater, leading to a decrease in density.
D. The formation of sea ice removes freshwater, leaving dissolved solids behind and increasing the density of seawater.
The formation of sea ice removes freshwater and dissolved solids from seawater, leading to a decrease in density. The correct option is C.
What is salinity?The concentration levels of salts in water or soils are referred to as "salinity."
Salinity is classified into three types based on its cause: primary salinity (also known as innate salinity), secondary salinity (also known as dryland salinity), and supplementary salinity (also called irrigation salinity).
When the water table rises, natural salts rise to the surface; in sufficient quantities, these salts become toxic to most plants.
As a result, the surrounding seawater becomes saltier because salt is left behind when sea ice forms.
As seawater becomes saltier, its density rises and it begins to sink. Surface water is drawn in to replace sinking water, which eventually cools and salts enough to sink.
Thus, the correct option is C.

Which of the following anatomical directions are opposites?
A. Anterior and posterior
B. Posterior and superior
C. Anterior and superior
D. Posterior and inferior
The anatomical directions that are opposites of each other are: Option D. Posterior and inferior . Anatomical directions refer to a standard frame of reference used to describe the locations and orientation of body structures.
The following anatomical directions are opposites of each other:Anterior (front) and posterior (back): These are opposites and refer to the front and back sides of the body. The front side of the body is the anterior side, whereas the back side of the body is the posterior side.
Superior (upper) and inferior (lower): These are opposites and refer to the upper and lower portions of the body. The upper side of the body is the superior side, whereas the lower side of the body is the inferior side. Medial (towards the midline) and lateral (away from the midline):
These are opposites and refer to the sides of the body. The side of the body that is closer to the midline is the medial side, whereas the side of the body that is further away from the midline is the lateral side. Proximal (closer to the trunk) and distal (further away from the trunk):
These are opposites and refer to the position of limbs or body parts relative to the trunk. The part of the limb or body that is closer to the trunk is the proximal part, whereas the part of the limb or body that is further away from the trunk is the distal part. Option D is correct.

Read the information for transcription and then answer the question.
Protein Synthesis
Explain the process of transcription
Answer:
Protein synthesis is the process which synthesizes proteins by the information coded in the DNA molecule with the help of two distinct process takes place in order namely transcription and translation.
Transcription is the first process of the central dogma or the protein synthesis that produces mRNA molecule that carries all the information stored in the DNA molecule out of the nucleus (in eukaryotes only) to the ribosome where the second process Translation takes place.
Untwists then unzips of DNA molecule is catalyzed by RNA polymerase result in the Hydrogen-bonds between the strands break .
Creates complementary base pairs with bases of the DNA strand with help of free RNA nucleotides
weak hydrogen bonds and sugar-phosphate bonds form between base pairs and RNA nucleotides respectively

Why are animal gametes haploid?
a. Gametes have two copies of each chromosome
b. Gametes are developing embryos that develop into haploid adults
c. Gametes have one copy of each chromosome to create a haploid individual
d. Haploid egg and sperm cells combine to create a diploid individual
Answer:
d. Haploid egg and sperm cells combine to create a diploid individual
Explanation:
Animals are diploid organisms (2n) and undergo sexual reproduction. This sexual reproduction causes them to produce gametes via a process called MEIOSIS. Meiosis is a division that reduced the number of chromosomes in the daughter cell (gamete) by half.
This means that meiotic division produces haploid gametes (n) from a diploid animal. This happens so that when the haploid sperm cell (male gametes) and haploid egg cell (female gametes) meet in a process called FERTILIZATION, a diploid individual is created.
Answer:
D. Haploid egg and sperm cells combine to create a diploid individual
