Answer:
An embryo sac is said to form when the haploid megaspore nucleus divides. It possesses two haploid nuclei and six haploid cells which do not have cell walls.

Answer: 4.How does the volume of water consumed affect the number of facial blemishes that individuals receive every month?
Explanation:
A hypothesis is a presumed explanation that is based upon few facts. The statement of the hypothesis can be verified by scientific procedures.
According to the given hypothesis, the relation of consumption of water with the number of facial blemishes is to be determined. Therefore, option 4 is the correct option.
Answer: C
SYNERGISTIC definition: relating to the interaction or cooperation of two or more organizations, substances, or other agents to produce a combined effect greater than the sum of their separate effects.
Biotechnology, by the word itself is a technology that is centered in
biology. It is the exploitation of biological process. Biotechnology has
harness the cellular and bio molecular processes to develop technologies and
product that help us elevate our lives. With the help of biotechnology, we are
able to modify the products for its specific use. Let me give you an example of
the following:
<span>1. </span>Medicine: In medicine, the modern biotechnology had
provided products that could combat rare diseases. Currently, around 250
biotechnology health care products and vaccines were made as well as those that
are known to be untreated.
<span>2. </span>Agriculture: With the help of biotechnology, we can
reduce some of the environmental footprint. It has been reported that it is
more than 13.3 million farmers used biotechnology products to prevent damage
from the yield cause by the pest.
<span>3. </span>Conservation: Biotechnology also help us reduce
greenhouse gas emissions.
Answer:
homo-zygous lethal dominant
Explanation:
A homo-zygous lethal pattern is a type of inheritance where an allele is lethal in homo-zygous individuals. In normal dominance, the expected genotype ratio when F1 heterozygous individuals are crossed is 1:2:1 (i.e. 1 homo-zygous dominant: 2 heterozygous individuals and 1 homo-zygous recessive), while the phenotypic ratio is 3:1 (3 individuals expressing the dominant allele: 1 individual only expressing the recessive allele). In this case, the homo-zygous lethal allele changes the expected F2 phenotypic ratio to 2:1 (i.e., 2 heterozygous singing Beetles : 1 homo-zygous recessive non-singing Beetles), where the partially dominant allele is lethal in homo-zygous individuals.
