Answer:
There's more carbon dioxide in the winter and a bit less in the summer. That's the collective breathing of all the plants in the Northern Hemisphere. "Plants are accumulating carbon in the spring and summer when they're active, and they're releasing carbon back to the air in the fall and winter," Graven explains.
Explanation:
Hope it helps.
Answer:
B
Explanation:
This may be rong, however I think this needs to happen before the mRNA can leave the nucleus. The cap helps prevent the mRNA from being destroyed by the cell itself once it leaves the nucleus.
Answer:
Testa, Protect, Desiccation, Feezer, Two, Cotyledons, Embryo , Plumule, Radicle
Explanation:
Seed germination is defined as the process of growing of a seed that involves causing a seed to sprout.
There are three primary parts seeds embryo, endosperm and seed coat. The outer covering of seed is called Testa which is seed coat that protects the seed from desiccation and external harmfull condition of environment.
The seed are stored in freezer that keeps it dry and cool. A temperature between 32° and 41°F is ideal for storing seeds.
Seeds are dvided into two halves called cotyledons. The new plant germinating is called an embryo which has two parts named plumule and radicle. Plumule grows into stem while radicle grow sinto root under favuorable conditions.
Hence, the correct answer in the blanks are Testa, Protect, Desiccation, Feezer, Two, Cotyledons, Embryo , Plumule, Radicle.
Answer:
Hello! Here are the answers:
- Chromosomes are a highly condensed form of a combination of DNA and protein called chromatin. DNA strands (negatively charged) are tightly wound around these proteins called histones (positively charged) to form chromosomes.
- Mechanism genes code for for proteins that govern life processes. These genes or portions of DNA are called exons. DNA segments between these exons are called introns that strictly code for regulatory proteins and also contain genetic regulatory elements (DNA sequences that control gene expression).
- Gene expression is the process of translation of DNA sequences into proteins. The genetic code is the nucleotide sequence in the DNA itself that codes for different amino acids that combine together to form a functional protein.
Explanation:
* 2. The intronic regions are misleadingly referred to as "junk DNA" but introns code for crucial regulatory elements that control gene expression.
* 3. The genetic code determines the sequence of amino acids in various proteins.
The reproductive system has four functions: To produce egg and sperm cells. To transport and sustain these cells. To nurture the developing offspring.
