Answer:
In plants and some protists, such as algae
Explanation:
Chloroplasts are organelles found in cells of plants and some protists, such as algae. They contain a pigment called chlorophyll, which makes them green. Thanks to this protein, they conduct photosynthesis - a process in which energy from sunlight is converted into sugars, i.e. food. In this process, oxygen is being released.

A student conducted an experiment with two rose plants to determine if a liquid formula for fertilizer produced greater growth than a dry formula. After testing each fertilizer on two different plants for one month, his data led to the conclusion that the liquid formula was a better promoter of plant growth. When he described his conclusion to his teacher, she told him he needed to conduct additional trials. The teacher most likely asked for additional trials because
Answer:
This question lacks options, the options are:
A) she did not believe the new formula helped plants grow better than the old formula.
B) it was necessary to see data from more plants before the conclusion could be accepted.
C) it was necessary to have tested the fertilizer on different kinds of plants.
D) she thought he should test additional fertilizer formulas on the same two plants.
The answer is B.
Explanation:
In an experiment, a TRIAL or RUN is refers to repetition of the experiment using the same procedure. A trial is done in order to ensure that the results of the experiment is not based on CHANCE but CERTAIN. It is important that before an experiment be accepted as valid, it must be able to be replicated severally.
In this case, a student conducted an experiment with two rose plants to determine if a liquid formula for fertilizer produced greater growth than a dry formula. However, after arriving at a conclusion based on his experimental results, his teacher told him he needed to conduct additional trials. This is because, according to the importance of trials above, IT WAS NECESSARY TO SEE DATA FROM PLANTS BEFORE THE CONCLUSION COULD BE ACCEPTED.
This, in essence, means the students need to repeat the test of the fertilizer formula on more rose plants.

What is the role of lactase? which sugar does the act on in reaction?
Answer:
This enzyme helps to digest lactose, a sugar found in milk and other dairy products. Lactase is produced by cells that line the walls of the small intestine. ... Lactase functions at the brush border to break down lactose into smaller sugars called glucose and galactose for absorption.
Explanation:
Lactase is an enzyme produced by many organisms. It is located in the brush border of the small intestine of humans and other mammals. Lactase is essential to the complete digestion of whole milk; it breaks down lactose, a sugar which gives milk its sweetness.

Some people can roll the tongue into a tube shape, while others cannot. Practicing is not likely to help because tongue-rolling is an inherited trait. The allele for rolling the tongue (R) is dominant to the allele for not being able to roll the tongue (r).
Create a Punnett square. Make sure that it shows a cross between two parents with at least one R allele.
The Punnett square, showing a cross between two parents with at least one R (rolling the tongue) allele, is mentioned below.
What is a Punnet square?A Punnett square is a graphical tool used by geneticists to predict the probability of offspring genotypes resulting from a cross between two parents with known genotypes.
In the Punnett square, the uppercase R represents the dominant allele for tongue rolling, and the lowercase r represents the recessive allele for not being able to roll the tongue.
The possible offspring genotypes are shown in the boxes within the table. The ratio of genotypes is 1:2:1, with 25% of the offspring having the homozygous dominant genotype (RR), 50% having the heterozygous genotype (Rr), and 25% having the homozygous recessive genotype (rr).

Answer:
w = 112
L = 64
Explanation:
L/w = 4/7
L = (4/7)w
---
2L + 2w = 352
2(4/7)w + 2w = 352
(8/7)w + (14/7)w = 352
(22/7)w = 352
w = 352*(7/22)
w = 112
L = (4/7)w
L = (4/7)*112
L = 64
