What is the effect of height on the velocity (kinetic energy) of an object?
2. The hot metal objects in the photo cool quickly
and soon stop glowing. What happens to the
energy as the metal parts cool?
Answer:
The molecules slow down, so the energy decreases.
Explanation:
Heat makes molecules move faster, and cooling makes them go slower.
A random mutation occurs and the gga code on this change to CGA what effect does the substitution have on the amino acid being called for explain your answer
Answer:The replacement of a base at a codon, as occurs when the GGA codon is changed to CGA, causes a change in the amino acid glycine to arginine.
Explanation:Nitrogen base changes in a codon usually result from base changes in the DNA before transcription into messenger RNA, called point gene mutations.
In the case presented, the substitution of the guanine base by cytosine in the GGA codon —resulting in a CGA codon— generates a change in the coding amino acid, resulting in arginine instead of glycine.
The change of an amino acid in a peptide or protein can mean an alteration in the structure or function of these molecules.
Because an amino acid can be encoded by several codons, changes of a nitrogen base at a codon sometimes do not involve changes in the amino acid sequence of a protein.
An example of a trait that is determined by multiple alleles is.
Answer:
Traits controlled by a single gene with more than two alleles are called multiple allele traits. An example is ABO blood type. Your blood type refers to which of certain proteins called antigens are found on your red blood cells.

Answer:
species-(i think?)...or maybe family?
Explanation:
well, it's basic genetics. if two organisms of the same species reproduce, a new organism of that species is born. however, if two organisms of different species reproduce, the offspring will be either nonexistent or hybrid. when an offspring is created, it belongs in the same family as its parents.

Why is genetic editing a bad thing?
Answer:
Although it has some good effects it can also harmfully reduce human diversity and increase social inequality majority of genetic editing is pretty bad.
It probably shouldn't even be allowed because it can cause risks to future children, creating new forms of discrimination. This can also make people lose their trust in science technology.
New toxins can be produced, Gene Transfer to Wild or Weedy Relatives, change in Herbicide Use Patterns. There are most Unkown harms yet to be discovered.
Answer:
it messes with genes. genes are important for forming organs and organ system in humans' early stages. Genes define the way we look. If we redefine genes, it may lead to abnormal consequences for humankind.
Genetically editing anything in general could cause serious complications in our world. It's almost like using our precious invention, life as a toy.

0.75
150
0.50
0.25
The frequency of the recessive allele in a population of 100 kangaroos having 50 dominant alleles is 0.75 which is called as the population genetics. So, the correct option is A.
What is Population genetics?Population genetics is defined as the subfield of genetics which deals with genetic differences within and between populations. It is a part of evolutionary biology where the study in this branch of biology investigates phenomena such as adaptation, speciation, and population structure.
Population genetics is described as the estimation of genotypic and allele frequencies in a population. In the given information, there are 100 kangaroos in the population where 50 of which are dominant, i.e. 25% dominant alleles. The frequency of the recessive allele in a population of 100 kangaroos having 50 dominant alleles is 0.75 which is called as the population genetics.
So, the correct option is A.

integrated pest management (ipm) is a pest control method founded on the principles of ecology. it involves using several control tactics based on a knowledge of the crop, pests and associated natural enemies. compared to traditional pesticide use on crops, how does a farmer implement ipm and what are the long-term goals?
The overall goal of IPM is to reduce the environmental and health risks of pesticides within social and economic constraints.
Fix: The scope of IPM implementation will continue to change greatly in the future. What began as limited approaches to promote integration of control methods for key pests and provide guidelines for decisions regarding pesticide applications is evolving to an ecologically-based systems approach.

Go outdoors and look for ten different plants. See if you can figure out which type of seed dispersal each plant uses, and make notes about each one. Some may have more than one method of dispersal. If you find a
plant that you suspect disperses seeds in a way that you haven't studied, try to figure out how the plant does it. When you're finished, write your discoveries in a list with the name of the plant you observed (if you
know it otherwise, describe the plant)
Some you wouldn't see by stepping outside, but it gives you a general understanding of what you should be looking for.

Which of the following are types of matter?
Check all that apply.
A. Substance
B. Mixture
C. Force
D. Compound
E. Sunlight
SUBMIT
Answer:
Explanation:
Gravity: You can feel its effects and it is associated with mass, yet it doesn't consist of matter. Memories: Like emotions, these are non-matter. Dreams: Again, you can't weigh them on a balance or enclose them in a container. Magnetism: Forces, in general, are not matter.
most matter is a mixture: It is composed of two or more types of matter that can be present in varying amounts and can be separated by physical means. Heterogeneous mixtures vary in composition from point to point; homogeneous mixtures have the same composition from point to point.
A substance is simply a pure form of matter. In other words, a substance is a matter that contains only one type of atom or molecule. Pure substances can be further divided into two sub-categories: elements and compounds.
Note that a compound: consists of atoms of two or more different elements bound together, can be broken down into a simpler type of matter (elements) by chemical means (but not by physical means), has properties that are different from its component elements, and.
No, sunlight is not a matter because it does not occupy space. Sunlight is a form of electromagnetic radiation and is made of small particles called photons.

Study Island
A marine biology team is studying a marine ecosystem near a shallow coral reef. For their study, they install ten stations, each supplied with a thermometer and a video camera. The thermometers measure the water temperature, and the video cameras monitor the activity of the fish in each location.
The team takes turns watching the video and determines the average activity of the different fish species at different water temperatures over many months.
After the study, the team reports the average activity and not the actual number of active fish because
A. they ran out of time to watch all the video.
B. they were too lazy to count all the fish.
C. average measurements simplify a complex system.
D. the average of a system is more complicated to measure.
Answer:
D: Average measurements simplify a complex system
Explanation:
"A marine ecosystem is too complex for anyone to accurately measure the exact number of active fish. Instead, a limited number of measurements is used to find a reliable average.
Averages help to simplify a complex system and make it more understandable. When a system is very complex, people depend on summaries, averages, and examples to improve their understanding of the system."

Which of the following statements about tolerance range is true? a. Tolerance range is different for different organisms. B. The tolerance range is the total number of organisms that can be supported by an ecosystem. C. Tolerance range is affected by biotic factors in an ecosystem. D. The available water supply does not impact an organism’s tolerance range. Please select the best answer from the choices provided A B C D.
The tolerance range is the limit of the abiotic factors in which an organism can survive. It has maximum and minimum limits. The tolerance range of different animal varies.
What is the Tolerance range?The tolerance range is the availability of the abiotic factors in the ecosystem of the species that is maintained and used by the species for survival and functional activities.
It is different for the various organisms as it is affected by the availability and ecosystem of the species. Some of the common abiotic factors are climate, water, temperature, trees etc. Too many and too less factors affect the organism.
Therefore, option a. tolerance range varies for the organisms.
