Answer:
Cell of and integument
Explanation:
When flowering plants reproduce by sexual reproduction, they form seeds contained into fruits. The fruit is derived from the maturation of the flower's ovary (female part) after fertilization.
A mature seed contains three generations:
- a diploid embryo (the new sporophyte),
- The embryo is surrounded by haploid female gametophyte tissue that supplies nutrition
- All the above structure is in turn surrounded by the seed coat (diploid parental sporophyte tissue). The seed coat is produced by integument cells to protect the embryo during its development and before its can germinate. As it is produce by it parental plant, its ploidy level diploid.
In contrast, the generative nucleus and sperm cell are part of male gametophyte (pollen grain) and therefore haploids. Synergid cell is part of embryo sac, therefore belongs to female gametophyte and thus being haploid. Finally, cell of endosperm is usually derived from the fusion between a sperm cell and one of the two female gametes present within the embryo sac, thus being triploid.
(a) solute = substance (solid or liquid) in lesser amount, which will [dis]solve into the solvent
(b) solvent = substance (liquid) in larger amount, which [dis]solves the solvent
it's dissolvability is called "solvency"
water is known as the universal solvent because it is abundant on Earth and has a high solvency
(c) solution = the combination of solvent + solute
depending on the saturation of solute within solvent, the solution may appear clear, like the solvent
**think of warm sugar-water (solution), when all the sugar (solute) dissolves into the water (solvent), the solute seems to have disappeared
Answer:
Option B
Explanation:
Complete question -
Following their sixteen-week, closed-ended, grief and loss psychotherapy group with adults as reported by Price et al, which of Yalom's therapeutic factors was most identifiable?
a. recapitulation
b. altruism
c. universality
d. imagery
Solutions -
Out of the eleven therapeutic factors the one that will be easily recognizable will be the one which will involve some kind of action and interaction or any visible signs. Altruism would affect a person positively and help him/her to gain confidence. This confidence will be visible by the person’s action when he/she will help other people in the group to gain value and significance in the same way as he/she has done.
Hence, option B is correct
B
The wastes are radioactive and can cause cancer. This is the #1 reason according to my research why it is important to dispose of nuclear waste.
Answer:
The correct option is;
A, B, and C, only
Explanation:
The amino group is the functional group of the form CH-NH₂ consisting of single bonds formed between hydrogen atoms, aryl groups, alkyl groups or two or more of such groups combined together bonded with a nitrogen atom. An amine is an organic compound that has an amino group in its composition or structure
Therefore, the amino group can be found in the molecules of A, B, and C only.
