Does each square on a "punnet square" represent 4 offspring or does it represent the odds of one offspring?
Answer:
Explanation:
Punnet square is a square diagram used to predict the genotypes of the offspring of a particular cross or breeding experiment.
It represent 4 offsprings of the cross between two parents. Each punnet contain the alleles in the right combination and proportion.
Punnet square is use to determine the percentages of different genotypes present in the offspring of two parents and to determine missing alleles in a cross.
it can also be used to predict the percentages of phenotypes in the offspring usually from a parents with known genotypes.
Where am I? I am a very large part of the World. Very few trees grow here. Eight countries have land here. I never get warmer than 50 degrees Fahrenheit or 10 degrees Celsius in the summer. Certain lights are viewed best from here. I have my own ocean. I also have my own circle. Where am ?
Answer:
north pole area
Explanation:
1. The north pole (very northern canada greenland and russia) is a big part of the world, but it's growing smaller
2. It's all mostly ice, so barely any trees
3. SUPER cold there, so it doesn't get warmer than 50 f or 10 c

How does a mouse reproduce ?
Answer:
Mice are breeding machines. They have a gestating period of 19 to 21 days. A female mouse gets pregnant about 5 to 10 times each year and can give birth to a litter of 3 to 15 pups. On average, a female mouse atleast give birth to 35 to 56 pups. The mice reproduce each year, and the mother can mate immediately after giving birth.

Explain the theory of evolution
please
As a consequence those individuals most suited to their environment survive and, given enough time, the species will gradually evolve.
Answer:
Explanation:
evolution is fueled by something called natural sellectoin to explain this lets say a species of birds move to an island where there are more seeds the ones that are able to eat will survive and reproduce and they will reproduce most times they will overproduce so there is a higher chance of surviving and there bodys will slowly change like the mucles will become stronger along with the beak that is baisicly evolution but this does take millions of years this not a few years and they change this is s extremly slow change.

A diagram that shows the amount of energy that moves from one feeding level to another in a food web is
A: food chain
B: energy pyramid
C: ecosystem
D: niche
Energy plays a important role in the propagation of life in ecosystems. Food chain shows the amount of energy that moves from one feeding level to another in a food web. Thus, the correct option is A.
What is food chain?A food chain is defined as the order of events in an ecosystem, where one living organism eats another organism, and later that organism is consumed by another larger organism.
The flow of nutrients and energy from one organism to another at different trophic levels forms a food chain. A system of interlocking food chains is called a food web.

What are the 2 main components of the Central Nervous System?
Answer || The central nervous system and the peripheral nervous system.
The nervous system is a complex system that is made up of nerves and nerve centers in different organisms that carries messages to and from the brain and the spinal cord to send them into various parts of the body.
It is primarily divided into :
1 ) CNS that is central nervous system ( made up of brain and spinal cord). The CNS is responsible for the voluntary functions of the body.
2 ) PNS that is peripheral nervous system ( possess cranial and spinal nerves arising from brain and spinal cord respectively). It controls the involuntary functions of the body.

A. The mass of the egg white increases as the volume of the enzyme increases
B.The egg white is unaffected by the differing amounts of enzyme
C. Digestion decreases in each stomach as more of the egg whites surface area becomes exposed
D. Digestion increases as the volume of the enzyme increases
Answer:
D
Explanation:
The correct answer would be that digestion increases as the volume of the enzyme increases.
Protein digestion is catalyzed by the pepsin enzyme and aided by HCl. The combined actions of both substances form the basis for the digestion of protein in the stomach. Hence, one would expect the digestion of the boiled egg white to increase with the increase in the volume of the enzyme - all other factors remaining constant.
The correct option is, therefore, D.

A.sperm cell
B. red blood cell
C. heart cell
D.skin cell
Answer: process in genetics by which the two chromosomes of a homologous pair exchange equal segments with each other
Explanation: sperm cells
CROSSING OVER:
Crossing over is a unique process that occurs only during meiotic division. Crossing over, also called recombination, occurs during prophase I of meiosis. Crossing over is the process by which non-sister chromatids of homologous chromosomes (a pair of similar but non-identical chromosomes from each parent). Crossing over ensures genetic diversity in the gametes (daughter cells) produced from meiosis:MEIOSIS:
Meiosis is the type of cellular division employed by sexual reproducing organisms to create sex cells or gametes. Meiosis produces four genetically different daughter cells called gametes. Sperm cells are gametes produced by male organism while egg cells are gametes produced by female organisms.Learn more: https://brainly.com/question/18824252?referrer=searchResults
What happens to most of the sunlight
energy that reaches the earth?
Answer: In explanation
Explanation:
Once the sun's energy reaches earth, it is intercepted first by the atmosphere. A small part of the sun's energy is directly absorbed, particularly by certain gases such as ozone and water vapor. Some of the sun's energy is reflected back to space by clouds and the earth's surface.

Use the picture to explain how CONVECTION heat transfers could be responsible for the weather in our atmosphere.
Answer the question in 2-3 complete sentences.
Answer:
The sun's waves heat the ground, causing it to warm (radiation). The energy flows from the warmer ground to the cooler air (conduction), causing it to rise (convection). When the rising air reaches a certain point, it expands, cools, and the cooler expanded air can no longer hold as much water vapor so it rains.

Answer:
Reducing the use of fossil fuels in vehicles.
Explanation:
Reducing the use of fossil fuels in vehicles and use of electric vehicles which reduces air pollution as a result decrease or slow down of global warming occur. Use of fossil fuels is the main reason for increasing carbon concentration in the environment. If more plants were planted around the world the high concentration of carbon decreases in the environment due t photosynthesis of plants. Avoid use of activities that increases the carbon concentration in the environment.
How does the operator region of DNA work to regulate gene expression?
Answer:
Explanation:
Operator region are region of DNA (deoxyribonucliec acid) that repressors protein binds to prevent transcription.
Repressor is an example of regulatory protein they regulate the rate at which transcription of operon occurs . A repressor functions when its bounded to the operator and it prevent enzyme RNA (ribonucliec acid)polymerase from moving to DNA to transcribe the nitrogenous bases by placing a complementary base pair.
Activators are other regulatory proteins that bounds to its DNA binding site and increases transcription of the operon.
