Plants That We Reconize Today Spend The Majority Of Their Life In The BlankA) Haploid Phase B) Seed PhaseC)

Answers

Answer 1

Answer:

The answer is C diploid Phase

Answer 2

Answer:

The answer is C.

Explanation:

Plants that we reconize today spend the majority of their life in the diploid phase.

During the sporophyte phase, a diploid plant body (one with two sets of chromosomes) develops and finally generates spores via the process of meiosis. Mitotic division of these spores results in the formation of gametophytes, which are gamete-producing organisms that are haploid (have a single pair of chromosomes).

1. What happened to the pH of the substances when the size of the sample was increased or
decreased?

2. What happened to the pH when the sample was diluted? Did the material change from its original classification as an acid/base/ or neutral?

3. Describe a neutralizing reaction and give the neutral products?

4. Predict the general pH that is the result of combining a strong acid with a weak base?

Answers

Explanation:

An acid-base reaction or neutralization reaction is a chemical reaction that occurs between an acid, for example hydrochloric acid, and a base, sodium hydroxide.

The word "salt" describes any ionic compound whose cation comes from a base (Na + from NaOH) and whose anion comes from an acid (Cl- from HCl). Neutralization reactions are generally exothermic, which means that they give off energy in the form of heat. They are often called neutralization because when an acid reacts with a base, they neutralize each other's properties.

There are several concepts that provide alternative definitions for the reaction mechanisms involved in these reactions, and their application to related problems in solution. The word neutralization can be interpreted as annihilation or as elimination, which is not far from the truth. When an acid is mixed with a base both species react to different degrees that depend largely on the concentrations and volumes of the acid and the base can be considered as an illustration the reaction of a strong acid that is mixed with a weak base, this The latter will be completely neutralized, while a portion of the strong acid will remain in solution, depending on the moles that reacted with the base. Three additional alternatives that arise from mixing an acid with a base can be considered:

A strong acid is mixed with a strong base: When this happens, the species that will remain in solution will be the one that is in greater quantity than the other.A weak acid is mixed with a strong base: The solution will be basic, since it will be the base that remains in the reaction.A weak acid is mixed with a weak base: If this happens, the acidity of a solution will depend on the acid constant of the weak acid and the concentrations of both the base and the acid.Despite the differences in definitions, its importance is evident in the different methods of analysis, when applied to acid-base reactions of gaseous or liquid species, or when the acidic or basic character may be somewhat less evident. The first of these scientific concepts of acids and bases was provided by the father of chemistry, the Frenchman Antoine Lavoisier, around 1776.

Environmental factors typically activate genes in a cell by causing the cell to --
A.produce identical daughter cells through mitosis
B.form haploid gamete cells through meiosis
C.fuse with another cell to increase the size of its genome
D.transcribe specific DNA segments to mRNA for translation

Answers

Environmental factors typically activate genes in a cell by causing the cell to transcribe specific DNA segments to mRNA for translation.

This interaction is an example of environmental factors affecting genetic expression. In these situations, the environment causes specific segments of DNA to be expressed, meaning they are transcribed to mRNA and subsequently used to form proteins.

Meanwhile, other parts of the genome remain or are forced to be silent. This can be a result of mutations or simple biochemical reactions between the environment and the genome.

The independent variable should stay constant because  each group should be completely different to do an experiment while it is being conducted.

What are variables?

The variables are defined as any characteristics, number or quantity which can be measured . They can also be called as a data item . They are called as variables because they can vary and can have variety of values.

There are three types of variables 1) manipulated variable where in a condition is specified, 2) responding variable which is dependent on manipulated variable 3)controlled variables which does not change

Example of manipulated variables are number of hours spent by a student studying , that of responding variable is result of a student and temperature is an example of controlled variable.

____________ diffuses out of the alveoli and into the pulmonary capillaries, while _______ diffuses out of the pulmonary capillaries and into the alveolar sacs.

Answers

Answer: Oxygen; Carbon Dioxide

Explanation:

Oxygen diffuses out of the alveoli and into the pulmonary capillaries, while carbon-dioxide diffuses out of the pulmonary capillaries and into the alveolar sacs.

What are pulmonary capillaries?

PULMONARY CAPILLARIES: Deoxygenated blood enters into the pulmonary arteries from the right side of the heart and is delivered to the pulmonary capillaries, the smallest blood vessels inside of the lungs, attached to the walls of the alveoli.

Moreover, oxygenated blood then passes from the capillary beds through venules into the pulmonary veins. The pulmonary veins transport it to the left atrium of the heart.

Therefore, the pulmonary arteries are the only arteries that carry deoxygenated blood, and the pulmonary veins are the only veins that carry oxygenated blood.
