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:
Sensory neurons
Explanation:
Neurons are specialized somatic cells which are responsible of conveying stimuli from the enviroment.
They are made up of three parts; cell body, dendrites and an axon.
Sensory neurons are one of the three types of neurons.
They are responsible of carrying stimuli from external body parts to the central nervous system.
On the other hand, motor neurons carries signals from the brain to other body organs.
The third type is called interneuron, it is located in the brain and nowhere else. It acts as a linkage between other neurons and the brain.
Answer:
D
Explanation:
This involves a dihybrid inheritance I.e. two genes are being passed on. During meiosis, specifically, the Prophase stage, homologous chromosomes (similar but non-identical chromosomes received from each parent) line side by side. According to the question, one chromosome contains A and B alleles and its homologue, received by the other parent carries a and b alleles. This means that the diploid individual has a genotype AaBb for that gene.
According to Mendel's law of independent assortment, the alleles separate independently of one another into gametes. I.e. allele A and a separates into the gametes without affecting alleles B and b of the other gene.
Crossing-over, which is the exchange of chromosomal segment occurs between the two homologues. Hence, the exchange of chromosomal segments containing alleles in the individual will possibly produce four gametes with the genotypes: AB, Ab, aB, ab.
Answer:
d
Explanation:
<em>The correct answer would be that the food could only be made of carbohydrates.</em>
<u>Proteins contain other elements such as nitrogen and sulfur in addition to carbon, hydrogen, and oxygen while nucleic acids and triglycerides contain phosphorus in addition to carbon, hydrogen, and oxygen.</u>
The only chemical substance that contains carbon, oxygen and hydrogen is carbohydrates.
Correct option: d
There are twice the number of Hydrogen atoms than Oxygen atoms in a disaccharide.
<h3>Disaccharides</h3>
- Disaccharides are carbohydrate compounds containing two monosaccharide units linked together by glycosidic bonds
Examples of disaccharides include sucrose and maltose.
- The ratio of hydrogen to oxygen atoms in a carbohydrate is always a 2:1.
For example, the formula of sucrose is C₁₂H₂₂O₁₁
> The ratio of hydrogen to oxygen atoms is 2;1
Therefore, there are twice the number of Hydrogen atoms than Oxygen atoms in a disaccharide.
