Answer:
step 3
Explanation:
A student will measure and record the growth (in height) of two flowering plants every other day for 20 days. Each plant will receive 200mL of water each day, but only one plant will receive 10mL of fertilizer. whats the independent variable, dependant variable, and the standardized variable?
Answer:
The correct answer is -
the independent variable - if fertilizer added or not,
the dependant variable - the height of the plant and
the standardized variable - 200ml water
Explanation:
In this study, the student wanted to see the effect of the fertilizer on the growth of the plant so the independent variable is the treatment of the fertilizer as manipulated or the independent variable is the factor which is affected or changed purposely during an experiment while other variables remain constant.
The dependent variable is the factor that is based or depends on the independent variable and measured to see the effect which is the height of the plants in this case.
The standardized or the control variable is the variable that remains constant throughout the experiment, 200 ml water treatment is the control variable in this experiment.
Which student will most likely overcome their nerves?
A.one who thinks positively and practices the speech in advance
B.one who thinks positively and stays up late to practice the speech
C.one who gets plenty of rest and eats sugary foods for energy
D.one who gets plenty of rest and avoids practicing the speech
Answer:
A.one who thinks positively and practices the speech in advance
Explanation:
It makes more sense
Student will overcome their nerves who thinks positively and practices the speech in advance
Positive behaviourThe person who thinks positively and practices the speech in advance will most likely overcome their nerves because the positive behaviour has good effect on the personality of an individual. Those people who think negative, they will not get success in their life.
Practice's benefitsThere is a saying that practice makes a man perfect. That person who regularly practice a specific topic, they can do the speech very well or other things in their life so we can conclude that student will overcome their nerves who thinks positively and practices the speech in advance.

a. 1-dissolved in plasma, 2- Hb
b. 1-Hb, 2-HCO3, 3-dissolved in plasma
c. 1- dissolved in plasma, 2-Hb, 3-HCO3
d. 1-dissolved in plasma, 2-HCO3, 3-Hb
e. 1-HCO3, 2-Hb, 3-dissovled in plasma
f. 1- Hb, 2-dissolved in plasma
Answer:
f. 1- Hb; 2- dissolved in plasma
Explanation:
Transport of oxygen in the body occurs in two way; oxygen bound to hemoglobin and oxygen dissolved in plasma.
1. Bound to hemoglobin :
Hemoglobin, or Hb, is a protein molecule found in red blood cells and is responsible for the colour of red blood cells. It is composed of four subunits of two types of the protein globin: two alpha subunits and two beta subunits. Each subunit surrounds a central heme group (red in color) that can bind one oxygen molecule.Therefore, each hemoglobin molecule can bind and transport four oxygen molecules. About 98.5% of oxygen is transported in the body bound to hemoglobin.
2. Oxygen is only fairly soluble in blood plasma. As a result, only 1.5 percent of oxygen in the blood is dissolved and transported in blood plasma.

Answer: the answer is c
Explanation:
Different types of cells occurs in organisms. These cells differentiate right from the zygote stage to become more specialized as the individual grow.
The two classes of cells found in the human body include the sex cells and somatic cells (option C).
These two main classes encompasses all the various types of specialized cells. The somatic cells are also called the body cells. These cells are diploid in nature. While the sex cells are also known as the gametes. The sex cells include the sperm cell from the male and the egg cell from the female. In humans there are 22 pairs of body cells (autosomes) and a pair of sex chromosomes (XX for females and XY for males).Learn more about the sex and body cells: https://brainly.com/question/927903

Answer:
Alvin is propelled by _gas or diesel___ hydraulic thrusters and features an electrical system powered by lead-acid batteries.
Explanation:
Technically, this implies that Alvin is working on motor-assist mode, using a hybrid engine. Alvin is, therefore, propelled by an internal combustion engine (given the presence of hydraulic thrusters) in addition to an electric motor, which uses energy stored in (lead-acid) batteries. Alvin must be a robot.

In which structure would you expect to find a chloroplast?
A. Blood cell from a dog
B. Cell from sunflower leaf
C. Human skin cell
D. Liver cell from a penguin
Answer:
b.cell from a sunflower leaf
The structure that can have chloroplast is the cell from sunflower leaf. The correct option is B.
What is chloroplast?Chloroplasts are chlorophyll-containing organelles found in plant cells; they are necessary for Earth life because photosynthesis occurs in chloroplasts.
Proplastids give rise to chloroplasts, as do chromoplasts, leucoplasts, as well as other plastids.
Chloroplasts are plant cell organelles that use photosynthetic energy to convert light energy into reasonably stable chemical energy.
They survive life on Earth by doing so. Chloroplasts also perform a variety of metabolic functions for plant cells, such as the generation of fatty acids and membrane lipids.
Chloroplasts are found in all green plants and algae. Chloroplasts can also be found in photosynthesis that don't appear green, such as giant kelp's brown blades or certain plants' red leaves.
Thus, the correct option is B.

Suppose that the narrow‑sense heritability of ear length in Reno rabbits is 0.4. The phenotypic variance (VP) is 0.5, and the environmental variance (VE) is 0.1. Calculate the additive genetic variance (VA) for ear length in these rabbits.
Answer:
0.20
Explanation:
The narrow-sense heritability, denoted by h², refers to the ratio of additive genetic variance (Va) to the total phenotypic variance (Vp).
Mathematically, it can be written as:
h² = V(A)/V(P)
Where;
V(A) = additive genetic variance
V(P) = total phenotypic variance
V(A) = V(P) × h²
Based on the information provided in the question, V(P) = 0.5, h² = 0.4
V(A) = 0.5 × 0.4
V(A) = 0.20
The additive genetic variance (VA) for ear length in these rabbits is 0.2.

At which point during meiosis do haploid cells first appear?
A. metaphase I
B. anaphasel
c. metaphase II
D. anaphase II
Answer:
D. anaphase II
Explanation:
The telophase is followed by short interphase in which, however, no DNA synthesis takes place, so this phase is not real interphase, which is why it is also called interkinesis. It is followed by another meiotic division, which also consists of four phases marked as prophase II, metaphase II, anaphase II when the spindle fibers pull the chromatids for the opposite poles and telophase II and represent a true mitotic division.
D. anaphase II
Haploid gametes are produced during meiosis, which is a type of cell division that reduces the number of chromosomes in a parent diploid cell by half.
The telophase is followed by short interphase in which, however, no DNA synthesis takes place, so this phase is not real interphase, which is why it is also called inter-kinesis.
It is followed by another meiotic division,
Prophase II: Starting cells are the haploid cells made in meiosis I. Chromosomes condense. Metaphase II: Chromosomes line up at the metaphase plate. Anaphase II: Sister chromatids separate to opposite ends of the cell. Telophase II: Newly forming gametes are haploid, and each chromosome now has just one chromatid.Therefore, correct option is D.

In gel electrophoresis, fragments are separated by size and electrical charge by applying __________ to them
Answer:
Gel matrix
Explanation:
Gel electrophoresis is a technique in molecular biology used to separate fragments of biomolecules such as DNA, RNA, protein by applying electric current through a GEL medium. The basis of separation of this fragments is their sizes and electrical charge.
In the gel electrophoresis procedure, a GEL medium made of Agarose is used. The DNA fragments, which are then negatively charged begins to move towards the positive end of the gel when electric current is supplied. The smaller fragments move/migrate faster than the larger ones towards the positive end. Therefore, In gel electrophoresis, fragments are separated by size and electrical charge by applying GEL to them.

What is the resulting amino sequence if the following mRNA molecule undergoes translation 5’ AUG AGU CCU CUU UGA 3’ ?
Answer:
From the translation of the mRNA molecule 5’ AUG AGU CCU CUU UGA 3’ results the amino acid sequence Met-Ser-Pro-Stop, that is, Methionine-Serine-Proline and the last triplet being a stop codon.
Explanation:
Messenger RNA (mRNA) molecule is in charge of conducting the encoded genetic information to produce the protein synthesis, organized in a sequence of nucleotides called the genetic code. The arrangement of the nucleotides is in triplets of bases or codons, which encode the synthesis of an amino acid (translation), determine the beginning of the synthesis and also establish the stop.
In the given sequence, 5’-AUG-AGU-CCU-CUU-UGA-3’ results the amino acid sequence Met-Ser-Pro-Stop:
5'-AUG Methionine (Met), being at the same time an initiating codon.AGU Serine (Ser).CCU Proline (Pro).UGA-3' is a stop codon.Stop codons do not code for amino acids, but their presence in a codon sequence marks the completion of peptide or protein synthesis.
