What are two tools used for sending information? cars and buses water and wind smoke and wood radio waves and lightwaves
Answer:
radio waves and lightwaves
Explanation:
Radio waves and light waves are both types of electromagnetic waves in the electromagnetic spectrum. Radio waves and light waves travel a particular distance and hence, are used to convey information over distances.
Based on this question, radiowaves and light waves are both tools used to send information. Radiowaves carry information from the station to the receiver, likewise light waves from one medium to another.

What is the difference between phenotype and genotype? A. Phenotype is the physical expression of a trait and genotype is all that alleles in the organism. B. Genotype is the physical expression of a trait and phenotype is all the alleles in the organism. C. Phenotype are the alleles that are mast in genotypes are the alleles that are expressed. D. Phenotype is when both allies are the same and genotype is when the alleles are different.
Answer:
A. Phenotype is the physical expression of a trait and genotype is all that alleles in the organism.
Explanation:
An organism's genotype is the combination of alleles found at a particular gene. The phenotype is how theses alleles are expressed to form a trait.
In a diploid organism there are two alleles for every gene. In simple Mendelian traits. one allele is dominant over the other, which is recessive. That means, that the phenotype displayed will be associated with the dominant allele whenever it is present.
Answer:
Explanation:
Phenotype -Physical
Genotype-Gene
What differentiates passive transport from active transport?

Identify the organelles in the cell. Label A Label B Label C Label D
Answer:
This question is incomplete
Explanation:
This question is incomplete but the completed/similar question with the diagram is in the attachment below.
First of all, the cell is a plant cell because of the presence of the large central vacuole present and also the green colour of the outer part of the cell (which is not a coincidence). Let's proceed to identifying the organelles.
Label A is the large central vacuole. This is not the nucleus as might be confused with because the nucleus is the next big reddish organelle to the right of the vacuole.
Label B is the cell wall. Because this is a plant cell, it has a cell wall which can be clearly seen to be the most outermost layer. While the next yellow boundary line is the plasma membrane.
Label C is the chloroplast. Recall from elementary biology that the chloroplast stores the green pigment chlorophyll. The green colour of this internal organelle makes it identifiable as the chloroplast.
Label D is the starch granule. The shiny semicrystalline structure of this organelle makes it identifiable as the starch granule.
Answer:
Chloroplast, Vacuole, Cell wall, Endoplasmic reticulum
Explanation:
Label A: Chloroplast
Label B: Vacuole
Label C: Cell wall
Label D: Endoplasmic reticulum

Explanation:
1. Melissa raises crickets at her pet store that she
sells for reptile food. She thinks that crickets
chirp more often when the temperature gets
warmer. She decides to conduct an experiment to
prove her theory
a. Manipulated variable
(IV)
b. Responding variable
(DV).
c. Controlled variable
d. Controlled variable
Hypothesis: If
then
because
_(manipulated variable)
(responding variable)
Answer:
a. Manipulated variable: TEMPERATURE
b. Responding variable: CRICKET CHIRP
c. Controlled variable: Same species of cricket
d. Hypothesis: IF the temperature is increased, THEN crickets will chirp more
Explanation:
Independent variable, also called the manipulated variable, is the variable that is changed or manipulated in an experiment. In this case, the independent variable is the TEMPERATURE.
Dependent or responding variable is the variable that responds to changes made to the independent variable. The dependent variable in this case is CHIRP OF THE CRICKETS.
Controlled variable is the variable that must be kept unchanged for all groups throughout the experiment. The controlled variable in this case is SAME SPECIES CRICKET USED.
Hypothesis is a testable explanation (via experimentation) to an observed problem or a given question. In this investigation involving Melissa, an hypothesis is: IF the temperature is increased, THEN crickets will chirp more.
