Answer:
puddle, rain, and cloud
the puddle will heat up and evaporate causing it to go into the sky
rain is when evaporated water condensates and forms a cloud once the water drops get to heavy they fall
and the cloud is caused by evaporated water condensating and thats when the water starts to cool down
In griffins, the allele for black feathers (B) is dominant over silver feathers (b) which are recessive. Two black griffins are crossed and have a silver offspring. What is the genotype of the parents?
Answer:
The correct answer is - Bb and Bb.
Explanation:
In this case, there are two traits decided by the black "B" allele that is dominant over "b" which is silver. In this case the cross between two black feather birds and the there would be genotype:
BB and BB or Bb and Bb or Bb and BB
1. In first case, and the third case, there is no or only one allele for the silver trait so the correct answer would be - Bb and Bb
B b
B Bb Bb
b Bb bb
thus, the correct answer is - bb which is silver feather.

What is Transpiration?Transpiration is the process by which moisture is carried through plants from roots to small pores on the underside of leaves, where it changes to vapor and is released to the atmosphere.
Transpiration is essentially evaporation of water from plant leaves. Transpiration is important because water is needed for photosynthesis and because water cools a plant off.
Thus, option "C" is the correct answer.

5 rules on how a feigned creature inherits traits
Answer:
Inherited traits include things such as hair color, eye color, muscle structure, bone structure, and even features like the shape of a nose. Inheritable traits are traits that get passed down from generation to the next generation. This might include things like passing red hair down in a family.

This looks like an earthquake
Explanation:
There doesn’t seem to be very much water present in the image which would be the cause for the rest of them
Hope this helps
Answer:
Earthquake
Explanation:
First off I wouldn't say landslide because if it was a landslide in more than likely would have cracked the concrete on the floor that the people are standing on and there would be more of a mess than what is show in the picture. Next I wouldn't say tsunami depending on how frequent this disaster was, if it was a tsunami more than likely most of that rubbish would have been soaked with water in other things that were in the water as well and I wouldn't say flood either because once again nothing is soaked with water with in that picture not even the concrete that the people are standing on so I say that the most reasonable answer would be earthquake due to them being know for destroying buildings alot.

What types of food molecules make up chicken? (Carbs, Proteins, and/or Fats?)
no links!!
but its fats right??
Answer:
Fats
Explanation:
Chicken contains many different amino acids with different R-groups. In particular, chicken contains a large number of Tryptophan amino acids, which are amino acids that contain the side chain known as “indole”.
The type of food molecules that make up chicken is Proteins. It generally contains about 20% of proteins.
What do you mean by Food molecules?Food molecules are those which give energy to living organisms and contain chemicals that are required for the growth and repair of cells and their functions in the body of living organisms.
Proteins are the polymers of amino acids, which are linked via peptide bonds. The side chains of amino acids are varied from one to another. These side chains provide stability to the amino acid sequence. Mostly, the side chain of tryptophan and arginine gives the makeup to the food molecules of chicken.
Therefore, the type of food molecules that make up chicken is Proteins.

Pesticide resistance is increasing, Farmers in the US tost 7% of their crops to pests in the 1940s, over the 1980s and 1990s, the loss
was 13%, despite more pesticides being used. It is estimated that 500-1000 pests have developed a resistance to pesticides. Consider
the diagram showing the evolution of pesticide resistance. Select ALL of the statements that do NOT accurately describe the
mechanisms of pesticide resistance shown in the graphic.
A)Insects that are sensitive to the pesticide all die out after the first
application, leaving only the resistant insects in the population,
B)When insects are exposed to the pesticide, some will develop a mutationmaking it resistant. Only these insects survive in the next generation
C)The first generation has an insect with a gene responsible for resistance toa pesticide. This allows it to survive the pesticide application and reproduce
D)The insect with the pesticide resistance gene reproduces. Because these insects are more likely to survive pesticide application, insects with this
trait become more prominent in the population
E)As a population of insects is exposed to a pesticide, those susceptible to
the pesticide will die out of the population, leaving those with a resistance
to survive and reproduce, becoming more common in the population
The insect with the pesticide resistance gene reproduces, these insects are more likely to survive pesticide application hence insects with this trait become more prominent in the population
What is a pesticide?A pesticide refers to a chemical that is used to control the spread of pests in the farm.
The question is incomplete but I will help you the much I can. We know that organisms that have favorable traits live long enough to reproduce and pass on these favorable traits to the next generation. Therefore, the insect with the pesticide resistance gene reproduces. Because these insects are more likely to survive pesticide application, insects with this trait become more prominent in the population

Which lake zone has phytoplankton?
A. Limenetic
B. Profundal
C. Benthic
D. Intertidal
Answer:
Option A is the correct one.
Explanation:
limnetic zone
The limnetic zone is the most photosynthetically-active zone of a lake since it is the primary habitat for planktonic species. Because phytoplankton populations are densest here, it is the zone most heavily responsible for oxygen production within the aquatic ecosystem
What are some things that determine human traits
Answer:
Traits are determined by genes, and also they are determined by the interaction with the environment with genes. And remember that genes are the messages in our DNA that define individual characteristics. So the trait is the manifestation of the product of a gene that is coded for by the DNA.
How are meiosis and mitosis different?
Answer:
Mitosis produces two diploid (2n) somatic cells that are genetically identical to each other and the original parent cell, whereas meiosis produces four haploid (n) gametes that are genetically unique from each other and the original parent (germ) cell.
Explanation:
:)
Answer: Mitosis produces two diploid (2n) somatic cells that are genetically identical to each other and the original parent cell, whereas meiosis produces four haploid (n) gametes that are genetically unique from each other and the original parent (germ) cell.
. Most of these differences relate back to the fact that, although both are needed for cell replication, mitosis and meiosis have different purposes: mitosis replaces body cells with identical copies, while meiosis creates genetically different sex cells that will be used to create an entirely new organism.

Horses and donkeys can breed and produce sterile offspring known as mules. Horses and donkeys remain separate species because of this hybrid sterility, which is a(n) Group of answer choices post-zygotic barrier to reproduction. sympatric barrier to reproduction. pre-zygotic barrier to reproduction. allopatric barrier to reproduction. good thing.
Answer:
The correct answer is ''post-zygotic barrier to reproduction''
Explanation:
Biological barriers prevent the exchange of genes between two or more populations, a postzygotic reproductive barrier reduces the survival or reproduction of hybrid offspring. In hybrid non-viability there is low survival of the hybrid, especially during embryonic stages. On the other hand, the sterility of the hybrid occurs when the fertilized egg develops into a healthy but sterile adult. Segregation of aneuploid gametes during meiosis, different gene associations occur on the chromosomes of the parents.

For example, plasma membrane proteins carry out functions as diverse as ferrying nutrients across the plasma membrane, receiving chemical signals from outside the cell, translating chemical signals into intracellular action, and sometimes anchoring the cell in a particular location.
Answer:
All cells have plasma membranes. Can molecules enter and leave the cell? Yes. The plasma membrane (also called the cell membrane), is a lipid barrier where molecule organelles live. The golgi ( a cell organelle) helps move the proteins across the plasma membarane. Proteins cannot move through the plasma membrane barrier by themselves because they are not small enough like water.

When rocks and minerals are worn and broken down into small pieces by water, wind, or ice, the resulting particles are called ?
Sand i think? Maybe dust tho if sand isnt an option
Explanation:
The resulting particles are called sediments.
Rocks and minerals are disintegrated by agents of weathering such as water, glacial (ice) and wind. When these agents of weathering act on rock and minerals, they break down into small particles. These small pieces of weathered rocks and minerals is what is called sediments.
Sediments are pieces of weathered materials from rocks and minerals which can be carried by agents of erosion and deposited in another location.
Thus, the resulting particles from the breakdown of rocks and minerals are called sediments.

Elements of xylem in a vascular bundle are lesser than those of phloem؟
Answer:
No.
Explanation:
No, elements of xylem in a vascular bundle are not lesser than those of phloem because of the division of xylem progenitor cells that increases the xylem concentration in vascular bundle. The vascular cambium forms more xylem tissue than phloem due to more division of the xylem progenitor cells. so in the light of this discussion we can say that xylem is more in concentration than phloem in a vascular bundle.
