What is the subject of a memoir? A. an experience or period in the author’s life B. a significant historical event C. a fictional adventure story D. an analysis of a certain topic

Answers

A. An experience or period in the author’s life.

Explanation:

A memoir is a story about an experience in someones life, but it has to be factual. A memoir can not be based on fiction, it has to be real and nonfictional.

Memoirs are usually told in first person, as it is recounting the occurrences that happened in ones life. It is different from an autobiography, as autobiographies usually focus on the whole lifespan of a person, while a memoir focuses on one topic or event that happened.

Memoirs also usually focus on personal growth throughout the writing, are truthful and keep track of the persons goals and influences.

For children who do not have galactosemia, what are their possible genotypes for this trait?

a pedigree chart for the inherited genetic condition galactosemia

heterozygous
homozygous dominant
homozygous recessive
no inheritance for this trait

Answers

Answer:

The correct answers are "heterozygous", and "homozygous dominant".

Explanation:

Galactosemia is a condition where people are not able to process the sugar galactose. People with this condition have one gene mutated, which does not allow the proper synthesis of the enzyme that breaks down galactose. Galactosemia is inherited as an autosomal recessive genetic condition, therefore, only children that are homozygous recessive develop the condition. Children that are heterozygous or homozygous dominant, will not develop galactosemia.

Answer:

its heterozygous and homozygous dominant

at very high tempratures enzyme molecules denatures due to high speed movements, at low tempratures enzymes works too slow to be useful enough.

low ph solotions contain lot of H+  and high ph solutions have few H+ , and the number of these H+ ions have polar effects on enzymes.  some Enzymes like pepsin works perfect in acidic environment ( ph=2)  while others might work at  high ph  or average ph( like Trypsin  works well at ph=7).

Explanation:

In DNA, there are 4 different nucleotide bases. Adenine (A), Thymine (T), Cytosine (C) and Guanine (G).

A (adenine) always pairs with T(thymine) and C(cytosine) always pairs with G (guanine).

If we have the strand:

ATCGGTCAAGCTAGG  

We have to pair A with T, and C with G. Therefore, the complementary strand of DNA will be:

Use the rose experiment to answer the question. What are the independent and dependent variables?

Answers

Answer:

Independent Variable - Amount of Light;

Dependent Variable - Plant Growth;

Controlled Variables - temperature, soil, container, and humidity

Explanation:

Independent Variable - Amount of Light;

Dependent Variable - Plant Growth;

Controlled Variables - temperature, soil, container, and humidity

1. Plants need light for it growth and development. By studying photosynthesis and chlorophyll one can  recognizes two factors: measure of light and development of a plant.  

The adjustment in light influences the development of a plant. Both the two factors are measurable.  

Cause-Independent Variable: measure of light  

Impact Dependent Variable: development of plant  

2. Plants have stems that become upward and roots that become descending. Become familiar with geotropism.  

Answer:

The rose experiment is not a specific experiment but refers to a general example used to explain the concept of variables in an experiment. In this example, let's say we want to study the effect of fertilizer on the growth of roses.

The independent variable in this experiment is the fertilizer. It is the variable that is manipulated or changed by the experimenter. In other words, the experimenter decides how much fertilizer to apply to each group of roses.

The dependent variable in this experiment is the growth of the roses. It is the variable that is being measured and affected by the independent variable. In this case, the experimenter measures the height, number of leaves, and number of flowers for each group of roses, and this data is used to determine if the fertilizer had any effect on the growth of the roses.

Therefore, in the rose experiment, the independent variable is the amount of fertilizer applied to each group of roses, and the dependent variable is the growth of the roses, measured by their height, number of leaves, and number of flowers.
