Describe the process of water moving in and out of the cell.
Answer:
Water moves across cell membranes by diffusion, in a process known as osmosis. Osmosis refers specifically to the movement of water across a semipermeable membrane, with the solvent (water, for example) moving from an area of low solute (dissolved material) concentration to an area of high solute concentration.

The cell part that helps with cell division is the ________
Answer:
centrioles
Explanation:
Every animal-like cell has two small organelles called centrioles. They are there to help the cell when it comes time to divide. They are put to work in both the process of mitosis and the process of meiosis.

An example of __ is the color of betta fish. When a RED fish (GG) is crossed with a YELLOW fish (gg), all of the offspring will be a ORANGE color (Gg)
Answer:
The correct answer is - incomplete dominance.
Explanation:
In the betta fish, there are different types of colors found in the fishes depends on the alleles present in their gene which follows incomplete dominance. Incomplete dominance is an inheritance pattern where a dominant allele does not mask completely and produce a blend of both alleles if present in heterozygous condition.
In the question, It is stated that when a cross between RED fish (GG) and a YELLOW fish (gg) produce orange color fish as offspring (Gg) which is a mix or blend of both alleles Red (dominant) and yellow (recessive).
During a laboratory experiment, you discover that an enzyme-catalyzed reaction has a △G of -20 kcal/mol. If you double the amount of enzyme in the reaction, what will be the △G for the new reaction?
A. +20 kcal/mol
B. -40 kcal/mol
C. -20 kcal/mol
D. -10 kcal/mol
Answer:
Option-C
Explanation:
Delta G (△G) refers to the overall energy released during a chemical reaction when equilibrium is reached i.e the rate of conversion of product into the substrate is equal to the rate of conversion of substrate into product. Thus, △G accounts for the equilibrium of the reaction.
In the given question, it has been mentioned that △G of a reaction is -20 kcal/mol then how will it change if the amount of enzyme is doubled.
The △G is not affected by the enzyme concentration as the presence of enzyme affects the G (Gibbs free energy) and activation energy.
Therefore, △G will remain the same even if the amount of enzyme is doubled i.e -20 kcal/mol will be the correct value.
Thus, Option-C is the correct answer.

Why are bananas curved?
Answer:
It's because of the sun! Bananas are curved so they can retrieve sunlight. Bananas go through a process called 'negative geotropism'.What it means is that bananas grow away from the ground, instead of growing towards it, hence the 'negative' geotropism.

What is the energy source that allows photosynthesis to occur?
Answer:
[tex]\boxed {\boxed {\sf The \ sun }}[/tex]
Explanation:
Photosynthesis is a special process that certain organisms (plants, algae, and some bacteria) undergo to create "food".
This turns light energy, carbon dioxide, and water into glucose and oxygen. The glucose becomes the food for the organism, because it is turned into ATP during cellular respiration. The ATP is energy that fuels the processes, like growth, repair, and transport.
This process occurs because of the sun. It provides the light energy needed for the reaction. Organelles inside of the cells, called chloroplasts, contain a pigment (chlorophyll) that captures this energy.
Color blindness is a X-linked recessive trait. A couple want to predict whether it would be possible for their child to be color blind. The female is an unaffected carrier and the male is red/green color blind. What percentage of offspring would be color blind?
Answer: There is a probability (n.b. NOT certainty) that half of all offspring will be colour blind.
Explanation: The female is XX and as an unaffected carrier we can assign genotype Cc where c is the recessive allele.
The male is XY and colour blind, so genotype cY
Male offspring can be cY or CY so p|colourblind = 50%
Female offspring can be Cc or cc so, again p= 50%
If there is also equal probability of sex of the offspring, there is an overall probability that half the offspring will be colour blind
Why is biodiversity important for ecosystems?
Answer:to stop from extinction
Explanation:
Use your knowledge of inheritance (the passing of traits from parents to offspring) to explain why
these twins look so different even though they have the same parents. Why aren't they identical? In
your answer you should include your knowledge of gametes (sperm and egg), chromosomes, and
variation
Answer:
Fraternal twins can be different genders because they are two completely different eggs getting fertilized; but even two same gender fraternal twins do not look completely alike. Whereas for identical twins since one egg is splitting into two, the two cells have the same exact DNA make up and chromosomes.
I also believe the technical part of it is to do with genetics, like ressesive and dominant genes, because they can be the same gender, ex. both girls and one has blue eyes, fair skin, and blonde hair, the other twin has brown eyes, black hair and tan skin. The parents could be part of the genes but there is also grandparents maybe the mom's mom has blonde hair and blue eyes, with fair skin. But the dad he has brown eyes, black hair and tan skin. The moms genes were recessive, but the grandma's genes were dominant.
I tried to explain it as best as I could I hope it helps!

what would happen if an electric fish was always negatively charged instead?
Answer:
Electric eels are part of a group of animals called electric fish.These cells pump positively charged sodium atoms, called ions, from inside themselves to the outside.
Explanation:
Brainliest? plz
Electric fish is a part of the group of animals which are responsible for producing charge. These organisms pump positively charged sodium ions from inside themselves to the outside environment.
What is electric fish?
An electric fish is an fish that can generate electric fields and transfer current through themselves. Most of the electric fishes are electroreceptive, which means that these fishes can sense the electric fields present in the environment. The only exception here is the stargazer family which is not electroreceptive.
The examples of electric fish includes Electric eel, that belongs to the genus Electrophorus, South American knifefishes responsible for the production of powerful electric shocks to stun prey.
If the electric fishes are supplied with the negative charge always then they will pump positive charge to neutralize the effect of that charge.
