Answer:
An egg cell is bigger than a sperm cell.
Explanation:
An egg cell is bigger than a sperm cell. Usually, the eggs are released during the woman’s menstrual cycle. When a baby girl is born, she is automatically born with millions of egg cells, while sperm cells are constantly being reproduced in males.One way in which the sperm cell is different from cells in the developing fetus is that the sperm cell is a haploid cell while the cells in developing fetus are diploid cells.
Sperm and egg cells are derived from meiotic division of parts of the male and female's reproductive organs respectively.
Meiosis, the division of sex cells, leads to daughter cells with half the genetic materials of the parent cells which are naturally diploid (2n). These daughter cells are also referred to haploid cells (n).
A fetus is formed from the combination of a haploid sperm (n) and a haploid egg (n) resulting in a diploid (2n) structure.
Thus, the cells in the developing fetus are diploid because they are formed from the combination of 2 haploid cells - the sperm and the egg.

Using careful observation, describe at least two differences between these two limbs. Start with the hand bones.
The wo differences between the hand bones of human and cat limbs are- Number of digits: Human hands have five digits (four fingers and a thumb), while cat paws have four digits. This difference in digit number is due to evolutionary adaptations that have occurred in the two species over time.
What are limbs?Limbs are the appendages of the body that are used for movement and manipulation. In humans and most animals, limbs typically consist of bones, muscles, tendons, ligaments, and other connective tissues that work together to produce a wide range of movements and actions.
Shape and size of bones: The bones in human hands are relatively long and slender, with distinct shapes and sizes for each digit. In contrast, the bones in cat paws are shorter and thicker, and the digits are more uniform in shape and size.
This difference in bone structure reflects the different functions of human hands and cat paws, as human hands are adapted for manual dexterity and fine motor control, while cat paws are adapted for hunting and climbing.
It's important to note that there are many other differences between human and cat limbs, including the structure and function of muscles, tendons, and ligaments, as well as the range of motion and flexibility of the joints.

why are side effects important for a drug
Answer:
Because if you take a drug normally without any side affects, you might get VERY sick. ( DON''T TAKE DRUGS UNLESS YOUR DOCTOR GIVES YOU SOME)
Explanation:
true or false; It is warmer in July than in January because the earth is closer to the sun in July.
Answer:
false
Explanation:
it’s actually the other way around! it’s farthest from the sun in july and closest in january! so instead of it being the distance between the sun, it’s actually caused by the tilt of earths axis!
Answer:
false!
Explanation:
the sun is actually closets to earth in January and the farthest from earth in July!

hey im not very good with science at all and i need help with this please
1. Consumers and producers both need nutrients to carry our life functions. On the other hand, producers are organisms that make their own food. Consumers are organisms that need to eat other organisms to obtain energy.
2. Decomposers play a critical role in the flow of energy through an ecosystem. They break apart dead organisms into simpler inorganic materials, making nutrients available to primary producers. Mold plays a big part in material biodegradation, enabling decay and rot necessary in all ecosystems.
3. The form of energy entering the food chain is sunlight, which is being taken by plants to produce glucose as their food energy. When it leaves the food chain, the energy is then heat.
4. The percentage of the energy stored by the grass that is passed onto the hawk is 1%
5. B because you can get more production from the cow's milk and meat.
Answer:
1.) Producers are organisms that are usually autotrophs and make their own food in the ecosystem by the process of Photosynthesis, using sunlight, to provide energy to themselves and later to consumers in the environment. Consumers on the other hand are organisms in an ecosystem that don't make their own food and get the energy from consuming producers, primary consumers or secondary consumers. There are 3 different types of consumers, herbivores, carnivores and omnivores.
2.) The roles of decomposers in an ecosystem is very crucial, they feed on dead and decaying bodies. Therefore these decomposers are in-charge or removing dead matter from ecosystem as well as giving energy back to the ecosystem, as where it started from.
3.) Energy enters a food chain in the form of sunlight, and leaves the food chain in the form of heat.
4.) grass = 100%; rabbit = 100% x 0.10 = 10%; hawk = 10% x 0.10 = 1%
5.) Option B, since receiving meat and milk and other dairy products would be more nutritious to the farmer's family than to eat corn most of the time

Watch the following video and write a scientific summary of your observations: https://youtu.be/jTSC4ntCPY4
Here are your goals for this assignment:
Observe and describe cheek cells
Summarize findings based on observations
Write a summary of your findings from this investigation. Be sure to include your personal observations as well as answering the questions below. (Answer all questions in full sentences.) Your summary should be 150 words or more.
What did you see in the microscope? Be specific and describe as a scientist would.
Did you see more than one cell in the microscope? How many?
Was the cell structure clearly visible? Describe it.
Could you make out any cell components? Which ones?
What did you find out from this investigation? Write a paragraph about your findings.
1, the cheek cell looks like a germ/bacteria and contain nucleus and other organelles.
2, In the microscope I see cheek cells just magnified.
3, No just cheek cells
4, no the cell was not that visible until he zoomed in
no
I found out the cheek cells are disgusting and should never lick them with my tongue.
Answer:
1. I don't have a microscope, the cheek cell looks like a germ/bacteria and contains a nucleus and other organelles.
2. In the microscope I saw several cheek cells, some clumped together, some separate.
3. Not really, they didn't have a pronounced shape.
4. No the cell was not that visible until he zoomed in
5. Not possible
The cheek cells grossed me out, the shape, and color. I found it weird to know that those cells are on our bodies. I honestly didn't learn much about them though.
I hope this helps! :)

3. Which statement describes starches, fats, proteins, and
nucleic acids?
A) They are used to store genetic information.
B) They are complex molecules made from smaller
molecules.
C) They are used to assemble larger inorganic
materials.
D) They are simple molecules used as energy
sources.
Answer:B
Explanation: Because if u Look at Protein Carbohydrates Nucleic acid and fatty acid actually they are polymers made up of small units called monomers.Option C is incorrect because these are organic molecules containing carbon so we cannot say that it will form an inorganic structures and the other option says about genetic information so genetic information is only determined by Nucleic acids not fatty acid, Protein or Carbohydrates and last option D is incorrect because nuclei acid didn't provide energy.
The statement which describes starches, fats, proteins and nucleic acids is they are complex molecules made from smaller molecules. So, the correct option is (B).
What are Nucleic Acids ?Nucleic acids are naturally occurring chemical compounds that break down to form a mixture of phosphoric acid, sugars, and organic bases (purines and pyrimidines). Nucleic acids are essential data-transmitting molecules of the cell, and, as they also direct the course of protein synthesis, they control the inherited characteristics of living things.
The two essential categories of Nucleic acids are Deoxyribonucleic acid (DNA) and Ribonucleic acid (RNA). DNA is the master prototype for life and contains genetic material in all free-living organisms and various viruses.
RNA is the genetic material of some viruses. It is also found in all living cells which plays an important role in certain processes like making proteins.
Thus, the statement which describes starches, fats, proteins and nucleic acids is they are complex molecules made from smaller molecules. So, the correct option is (B).
