Answer:
A food chain describes how energy and nutrients move through an ecosystem.
Explanation:
At the basic level there are plants that produce the energy, then it moves up to higher-level organisms like herbivores. After that when carnivores eat the herbivores, energy is transferred from one to the other.

A base pair (bp) is the pairing of two nucleobases located on two complementary strands of DNA or RNA. This pairing is carried out by hydrogen bridges. There are four types of nucleic bases: A-T-C-G, these letters Adenine, Thymine, Cytosine, and Guanine. A with T and C with G.
It is also necessary to take into account the antiparallel character of the DNA strands. If a strand is in the 5 '3' direction, its complete strand is in the 3 '5' direction.

Which of the following statements about plant reproduction is TRUE?
a. Plants only reproduce sexually.
b. Reproduction in plants usually requires windy environments.
c. Flower shape, color, and odor can attract animals needed for plant reproduction.
d. Reproduction in most plants requires honeybees to carry pollen from one plant to another.
Answer:
D
Explanation:
A is wrong since plants reproduce sexually and asexually.
B is not logical since plants do not need windy environments for reproduction.
C is not logical either since animals and plants do not reproduce.
D is the most logical answer since honey bees play an important role in pollinating plants and carrying pollen from one plant to another since plants can not move and are autotrophs.
Reproduction in most plants requires honeybees to carry pollen from one plant to another is true about plants reproduction.
What do you mean by plant reproduction?Plant reproduction is the production of new offspring in plants, which can be accomplished by sexual or asexual reproduction. Sexual reproduction produces offspring by the fusion of gametes, resulting in offspring genetically different from either parent.
The parent plants have male and female sex cells, called gametes. The genetic material from the male and female gametes combines to produce offspring. We call this process fertilization. The product of sexual reproduction are seeds.
Plant fertilization is the joining of male and female gametes, resulting in a zygote. The most generalized form of this process requires four steps: pollination, germination, penetration of the ovule, and fertilization.

Kyree is heterozygous. |f(W) ) is for waves, and ) if for no wave (w) r no waves What is Kyree's genotype & phenotype?
Answer:
Kyree b will have waves with a gwnotyoe; We
Explanation:
This question involves a single gene coding the possession or not of waves in humans. Allele W is for possession of waves while allele w is for no waves.
Heterozygous means contains two different alleles of the same gene. In this case, an heterozygous individual will possess allele W and w together i.e. Ww. Since the allele W is dominant over allele w i.e. can mask Its phenotypic expression, an heterozygous offspring (Ww) will phenotypically possess waves.
Which molecules are easily diffuse across the plasma membrane
Answer:
Water diffusion is called osmosis. Oxygen is a small molecule and it's nonpolar, so it easily passes through a cell membrane. Carbon dioxide, the byproduct of cell respiration, is small enough to readily diffuse out of a cell. Small uncharged lipid molecules can pass through the lipid innards of the membrane.

Which form of nitrogen is most abundant on earth? N2 (Atmospheric Nitrogen) NH3 (Ammonia) NO2- (Nitrite) NO3- (Nitrate)
Answer:
N2 (Atmospheric Nitrogen)
Explanation:
Nitrogen is a chemical element positioned as 7 on the periodic table. Nitrogen is found as a gas in the atmosphere (N2) and constitutes the most part of the air making it the most abundant gas on Earth.
Atmospheric nitrogen (N2) is the most abundant of its form found on Earth. It can be converted to its compound form e.g. nitrates (a plant usable form) by lightning and some bacteria in the soil.

Answer:
Exposure to sunlight.
Explanation:
Sunlight is important condition necessary for the presence of Marine life in ocean. This is because sunlight provide energy for ocean current and wind waves. When this energy is converted to heat, it a layer of warm water which is present at the ocean surface which support most Marine life. Sunlight produce light energy which is needed for Marine life like algae to photosynthesized in addition with carbondioxide and water in order to to produce necessary for survival for most Marine life.
