Monocots have only one seed leaf inside the seed coat. It is often only a thin leaf, because the endosperm to feed the new plant is not inside the seed leaf. Dicots have two seed leaves inside theseed coat. They are usually rounded and fat, because they contain the endosperm to feed the embryo plant. [Credit to: Monocots and Dicots - The seed site]
Answer:
The correct answer is: it would create a polyploidy.
Explanation:
Polyploidy consists of an organism or a cell having more than 2 pairs of chromosomes, which in most species (including humans) is abnormal and not compatible with life.
An organism with 3 sets of chromosomes -69 in total- (instead of 46) has a triploidy. In humans, this happens when there's an extra haploid set from one of the parents.
An organism with 4 sets of chromosomes -92 in total- has tetraploidy.
These polyploidies result in miscarriage.
Answer:
The correct answer is - overdominance.
Explanation:
In the given question, genotype Pp is a heterozygote condition that has a 54% survival rate or fitness thus these individual people get more chance of mating and increase in number as compared to the other two conditions of PP or pp traits where PP has 45% survivability, less than heterozygous condition and more than pp that has only 4% rate.
It results in a normalizing selection model of natural selection as a moderate trait, that is heterozygote, is selected. Thus, the selection of overdominance which means heterozygote condition produces a better phenotype than PP or pp parents is heterosis.
Answer:
Claim 5: Cells need glucose AND oxygen to release energy.
Explanation:
A cell can be defined as the fundamental or basic functional, structural and smallest unit of life for all living organisms. Some living organisms are unicellular while others are multicellular in nature.
A unicellular organism refers to a living organism that possess a single-cell while a multicellular organism has many (multiple) cells.
Cellular respiration can be defined as a series of metabolic reactions that typically occur in cells so as to produce energy in the form of adenosine triphosphate (ATP). During cellular respiration, high energy intermediates are created that can then be oxidized to make adenosine triphosphate (ATP). Therefore, the intermediary products are produced at the glycolysis and citric acid cycle stage through the breathing of oxygen used to obtain energy from the food ingested.
Hence, cells need glucose and oxygen to release energy.
The desert environment makes it difficult to take in water, so leaves that are small would adapt to the desert environment by trying to conserve the little water that they do receive. Therefore, your answer should be:
b. They minimize water loss.
