Answer:
Explanation:
Seaborgium is a synthetic chemical element with the symbol Sg and atomic number 106. It is named after the American nuclear chemist Glenn T. Seaborg. As a synthetic element, it can be created in a laboratory but is not found in nature. It is also radioactive; the most stable known isotope, 269Sg, has a half-life of ... nuclei (all positively charged) repel each other due to ...
Answer:
A. an embryo sac
Explanation:
Angiosperms or flowering plants produce their gametes through the meiosis.
In the ovule (contains female reproductive cells) a diploid cell (megaspore )undergoes meiosisin which four cells (megaspores) with haploid nuclei are produced. One of these four megaspores then undergoes three successive mitotic divisions to produce an immature embryo sac which is the megagametophyte with 8 haploid nuclei (3 antipodal cells, 2 synergid cells, 1 egg cell and 2 polar nuclei).
The majority of the water is kept from evaporating into the atmosphere because of the activities. Pollutants from the activities seep into the water table through the soil.
By generating erosion, conveying fertilizers, pesticides, and heavy metals, as well as by reducing the amount of water that naturally flows in streams and rivers, excessive irrigation can have a negative impact on water quality. When applied to a landscape, fertilizers and pesticides don't stay put; instead, runoff and infiltration carry these toxins into nearby rivers, streams, and wells. From subterranean storage tanks, hazardous liquids such as gasoline escape into the groundwater supply. Pollutants from poorly built septic systems or landfills seep into the groundwater. Runoff from fertilized fields, livestock regions, abandoned mines, salted roadways, and industrial locations pollutes groundwater.
Thus, the activities can be said to be the main reason why the majority of the water is prevented from evaporating into the atmosphere. Pollutants from the activities permeate through the soil and into the water table.

For the answer to the question above, I believe the answer to the question is that <span>the steroid receptor protein cannot enter the nucleus so the gene of interest is repressed even in the presence of the hormone. I hope this helps</span>
Answer:
Shape
Explanation:
The structure of a DNA sequence determines the function of a protein by it's shape. The shape of a protein is determined by the sequence of the amino acids which is also the primary structures. And then the sequence of amino acids are determined by the sequence of nucleotides in the genes, which encodes it.
Hope this helped!
