Hey there!
I think it's 2 & 3. Maybe 4 too
Hope this helps!
Always remember, you are a Work Of Art!

Answer:
If the two organisms are heterozygous for the dominant trait.
Explanation:
For every trait, a diploid organism receives two forms of gene called ALLELE, from each parent. Allele is the variant form of a gene.
According to Mendel's law of dominance, for a particular trait, an allele is capable of masking the expression of another allele in a gene. The expressed allele is called the DOMINANT allele while the masked allele is called the RECESSIVE allele. Due to this, an organism can express a dominant trait even in a combined or heterozygous state i.e. different alleles.
When the two heterozygous organisms mate or are crossed, they undergo meiosis and their alleles are separated into GAMETES according to Mendel's law of segregation. For example; an organism with genotype (genetic make-up) Aa will produce gametes with A and a alleles.
Note that, a recessive trait can only be expressed in a homozygous state i.e. same allele. Hence, the two heterozygous organisms will produce gametes containing the recessive allele, which will likely combine to produce a recessive phenotype or trait.
Proteins that are embedded within, and extend across, the phospholipid bilayer are called <u>Integral Protein</u>.
Integral Protein- Any protein containing a unique functional area for the purpose of ensuring its location within the cellular membrane is referred to as an integral protein, which is also referred to as an integral membrane protein. Or, to put it another way, an integral protein seizes the cellular membrane.
Cellular membrane- All cells have a cell membrane, also known as a plasma membrane, which divides the inside of the cell from the external environment. A semipermeable lipid bilayer makes up the cell membrane. The movement of materials into and out of the cell is controlled by the cell membrane.

Answer:
Explanation:
In a lake, oxygenic phototrophs produce new organic material as well as O₂. If primary production rates are very high, the resultant excessive organic matter production can lead to bottom-water O₂ depletion from respiration and the development of anoxic conditions. This in turn stimulates anaerobic metabolisms, including anaerobic respirations and fermentations.
Organic matter that is not consumed in surface layers sinks to the depths and is decomposed by anaerobes.
Answer:
The DNA of any individual possesses genetic traits which vary from individual to individual. Traits can be physical traits or behavioral traits.
Explanation:
Example of a physical trait would be the appearance of an individual and behavioral trait refers to the nature of the individual. Both vary from individual to individual.
