(Bottom to top)
Biosphere- The ecosystem comprimising the entire Earth & the living organisms that inhabit it. Example: Where life occurs on, Earth
Biome- A large naturally occuring community of plants and animals Example: Rainforest, Tundra, Desert, Marine, Grasslands, etc
Ecosystem- A community of living organisms called producers, conumers, decomposers. Example: Plants (Producers) Rabbits (Consumers) Worms (Decomposers)
Community- Interacting group of various species Example: A forest of trees inhabited by animals.
Population- Traits of a group of plants and animals Example: 4 rabbits have broenn fur and 2 have black fur in a group.
Individual- Individual organisms Example: An otter is a organism
Abiotic examples- Air, soil, sunlight, or water
Biotic examples- A frog, a leaf, or a tree

You splice DNA fragments from a "foreign" source into the patient's gene so that the gene will begin manufacturing the enzyme. T

Answer:

recombinant DNA

Explanation:

In molecular biology, recombinant DNA molecules are genetic sequences formed by combining DNA material from different sources (i.e., organisms, populations, species, etc). Proteins produced from DNA recombinant molecules are known as recombinant proteins. Molecular cloning is the most widely used technique in molecular biology in order to produce recombinant DNA molecules. In this technique, a cloning vector such as, for example, a plasmid of a bacterium, is used to insert a foreign DNA fragment into another cell which is then expressed in the host cell.

Please order the layers of a cliff side by the age of fossils found there from youngest to oldest

aev [14]

Youngest to oldest would be: 3, 4, 1, 5, 2. Since it's from the bottom, the ones furthest from the bottom would be the youngest at the top. The oldest fossils would be closest to the bottom.

2 Explain why fossil fuels contain large amounts of carbon compounds.

Korvikt [17]

Fossil fuels release carbon dioxide gas when they burn which adds to the greenhouse effect and increases global warming. Of the three fossil fuels, for a given amount of energy released, coal produces the most carbon dioxide and natural gas produces the least.

If an organism is homozygous for a particular trait, the organism A. has extra alleles on both chromosomes in a chromosome pair.

inysia [295]

B. Has the same allele on both chromosomes in a chromosome pair.

Here is why:

Homozygous means the same, while heterozygous means different. If both of the same alleles are on both chromosomes, then it will be a homozygous.

There can be two types of homozygous alleles.

Homozygous Dominant: BB

Homozygous Recessive: bb

Notice in both of these they were the same alleles.

Heterozygous: Bb

Notice how both are different alleles.

Below I have attached a diagram of a Punnett square I have made.

On the left is a homozygous recessive allele pair.

On the top is a heterozygous allele pair.

Which nerves are the hair cells in contact with?

AlekseyPX

Answer:

Auditory nerve

Explanation:

Hair cells form synapses with bipolar neurons whose axons form the auditory nerve. Tips of the outer hair cells are attached directly to the tectorial membrane. When the inner hair cells move they make contact with the overhanging tectorial membrane

Fun fact: Hair and nials are made out of the same things!
