Answer:
Conduction: This is a flow of heat by direct contact. Heat travels from a warmer object toward a colder object.
Convection: This is a transfer of heat by mixing a fluid. Convection occurs within liquids and gases. Examples include boiling water and when warm water mixes with cold water.

17. How does the placement of the stamen in relationship to the pistil affect the way in which
the flower is fertilized?
Answer:
this placement increases the chances of pollination
Explanation:
Pollination refers to the process of transferring pollen grains from the male stamens of a flower to the female stigma. The stamens generally surround the pistil and they are composed of two structures: 1-the anther (produces male reproductive cells or pollen grains) and 2-filaments (supports the anthers). Moreover, the female pistil is generally located at the center of the flower and it is composed of three structures: stigma (a sticky bulb in the center of flower), ovary (contains female reproductive cells or ovules), style (supports the stigma). The arrangement of the plant's reproductive organs increases the chances of pollination: when a pollinator (e.g. bees) visits a stigma for nectar it has to go through the stamen and catch pollen that then carries to the stigma of the same flower (auto-pollination) or another flower (cross-pollination). Moreover, the flowers also have petals and sepals that help attract pollinators and protect the flower bud, respectively.

5. What types of genes change very slowly?
Answer: Mutation. The allelic variations that make evolution possible are generated by the process of mutation, but new mutations change gene frequencies very slowly, because mutation rates are low. Assume that the gene allele A1 mutates to allele A2 at a rate m per generation and that at a given time the frequency of A1 is p.

Meteorologists often try to predict what the high temperature of a day will be several days beforehand. Why do meteorologists not try to predict the high temperature of a day six months in the future?
A. Weather does not follow any predictable patterns.
B. Meteorologists have this information but choose not to share it with the public.
C. It is impossible to know what season it will be six months in the future.
D. Weather is a highly complicated system that is very difficult to predict.
HELP
Answer:
Its D- Weather is a highly complicated system that is very difficult to predict.
Explanation:
Weather has a pattern so A is not the answer and no way Meteorologists would keep information to themselves so not B and lastly it's not impossible but just very hard so C is out, which leaves D.

Why are only four amino acids produced by 5 codons? I need this answer ASAP
Answer:
My answer (that the information we have about codon structure is limited to the observations we can make now) is similar to the first part of your answer: that the number of amino acids that can be encoded is a function of codon length, in that both imply the (circular) argument that we must need more than 14 amino acids (plus a start and a stop, making 16) because we observe three nucleotide codons rather than two nucleotide codons. It would be nice to have a noncircular argumentf for why the minimum number of distinct amino acids is more than 14, but that is beyond my ability to construct
A, T, C, and G are the only letters found in DNA, however, a protein may include up to 20 distinct amino acids. Codons assist in translating the DNA code into a protein code at this point.
What are genetic codons?For the body to develop and work effectively, 20 different amino acids are required. All 20 of them are crucial for your health, but only 9 are considered to be absolutely necessary.
This is due to the degeneracy of genetic codes, one of their characteristics, the remaining 3 codons are called "stop" codons since they do not code for any amino acids. The sequences UAA, UAG, and UGA include the stop codon information.
Therefore, only 61 of the 64 possible codon combinations code for amino acids.

Which best explains what occurred at point X on the curve?
A. The birth rate was equal to the death rate.
B. The death rate was greater than the birth rate.
C.The rate of emigration was equal to the birth rate.
D. The rate of immigration was greater than the death rate.
Answer:
A. The birth rate was equal to the death rate.
Explanation:
The point X is the carrying capacity and this pajae could be ascribed as the plateau stage of population growth, whereby the maximum number of individuals of a particular species which the environment can support has been reached. Hence, giving a long, flat area of the logistic growth curve. At the stage marked x, growth would seize as the population hovers to attain equilibrium with the natality and fatality rate becoming equal, that is birth rate will be equal to the death rate in the population.

what are two function of bile juice
Answer:
It aids in digestion, absorption, excretion, hormone metabolism and other functions. Bile juice is a digestive fluid produced by the liver. It is stored and concentrated in the gallbladder. Its main function is to convert fats in food into fatty acids, which are absorbed in the gut.
Explanation:
(1)The bile juice works as a medium to break down fats from larger parts to smaller parts of body for digestion. (2)The bile juice also functions as a substance that eradicates the germs from the food, making it more hygienic for our body.

Describe the bonding between ionic compounds
Answer:
Ionic bonding is the complete transfer of valence electron(s) between atoms. It is a type of chemical bond that generates two oppositely charged ions. In ionic bonds, the metal loses electrons to become a positively charged cation, whereas the nonmetal accepts those electrons to become a negatively charged anion.Explanation:

How does waste removal in a fetus differ from waste removal after birth?
A) Fetal waste is removed through the chorion; infant waste is removed through the rectum.
B) Fetal waste is removed through the rectum; infant waste is removed through the chorion.
C) Fetal waste is removed through the ductus venosus; infant waste is removed through the rectum.
D) Fetal waste is removed through the large intestine; infant waste is removed through the ductus venosus.
Answer: A) Fetal waste is removed through the chorion; infant waste is removed through the rectum.
Explanation:
A developing fetus is surrounded by chorion which is an outer membrane. The role of the chorion is to protect the embryo and provide nutrition to it in the form of blood supply. It helps in getting rid of waste products from the developing fetus that goes into the mother blood to remove out of her body. In case of infants the rectum is the last part of the digestive tract and it receives the waste in the form of fecal matter from small intestine which is removed out through the rectum.
