the same version of the studied trait. Which of the following best describes
these experiments?
O A. Mendel crossed true-breeding plants with different versions of a
studied trait.
O B. Mendel crossed plants that all expressed the same version of a
studied trait.
C. Mendel observed crosses that took place naturally in his gardens.
Ο Ο
O D. Mendel allowed true-breeding plants to self-pollinate.
Answer:
Mendel observed crosses that took place naturally in his gardens.
Explanation:
Traits are transmitted faithfully from parents to offspring independently of other traits and in dominant and recessive patterns. Mendel was interested in the offspring of two different parent plants, so he had to prevent self-pollination.

The photograph shows rockweed. Which feature allows rockweed to
withstand the constant wave action of its environment?
A. The ability to carry out chemosynthesis
B. The ability to firmly attach to rocks
C. The ability to produce its own light
D. The ability to carry out photosynthesis
Answer:
B
Explanation:
This is the answer because if the rockweed is able to firmly attach its self to the rocks it would be able to withstand the constant wave action
The tendency to firmly attach to rocks allows rockweed to withstand the constant wave action of its environment.
RockweedIt is a brown alga and grows in the rich intertidal zone.
The holdfast of a rockweed permits it to withstand the constant wave action of its surroundings.
Holdfast is a tiny stem-like composition which allows the weed to anchor firmly to the rocks.
The rockweeds possess some of the advantages over the normal weeds that permits them to sustain in water like the intense developed root systems.
Thus, the correct answer is option B, that is, the ability to firmly attach to rocks.

I got 100% on my psych test 2022 edge
Explanation:
Researchers are investigating the incidence of algal blooms in neighborhood ponds. In summer, they collect water samples from over 100 neighborhood ponds in Dallas, Texas and surrounding cities. They also surveyed residents in each neighborhood to collect data such as average lot size, average home value, average resident income, and lawn care methods. The researchers found that neighborhoods with large lots, high home values, and high income levels were likely to use automatic sprinklers and synthetic fertilizers on their lawns. These same neighborhoods were very likely to have abundant algae in their ponds. Based on this research, which conclusion below provides the best explanation for why algae proliferate in neighborhood ponds?
a. Automatic sprinklers may house algae and may spray into neighborhood ponds.
b. High income neighborhoods are less likely to treat their ponds with chemicals that prevent algae growth.
c. Lawn fertilizer that washes into neighborhood ponds likely causes algae to become more abundant.
d. Neighborhoods with expensive homes typically have larger, deeper ponds that are more likely to support algae proliferation.
e. Large lot sizes likely provide algae with extra room to grow, and the algae then washes into the pond.
Answer: c. Lawn fertilizer that washes into neighborhood ponds likely causes algae to become more abundant.
Explanation:
Eutrophication is a natural phenomena in which the algal growth occurs in the water body due to increase in concentration of the fertilizers and manures being drained from the agricultural land into water. This causes decrease in oxygen level in water, and the aquatic animals in water will not survive due to scarcity of water.
According to the given situation, the growth of algae in the neighboring ponds is due to the drainage of lawn fertilizers into the neighboring ponds being washed from the lawns. This causes algae to grow abundantly in ponds.

A: Proteins are assembled on ribosomes.
B: A large central vacuole stores DNA and RNA.
C: Mitochondria provide energy for cell processes.
D: Chloroplasts capture and transform the energy of sunlight.
E: The rough endoplasmic reticulum releases enzymes to break apart wastes.
Answer: A
Explanation: The correct answer is option A because it is the only answer where it occurs in both prokaryotic and eukaryotic cells.
Option A: Proteins are assembled on ribosomes. is correct.
Cells fall into following two broad categories.
Prokaryotic EukaryoticProkaryotes are single-celled creatures belonging to the Bacteria and Archaea domains. Eukaryotes include animal cells, plant cells, fungus, and protists. Prokaryotic cells do not have a nucleus. Cells with a nucleus are referred to be eukaryotic cells. Aside from the nucleus, eukaryotic cells have other organelles. Ribosomes are the only organelles in a bacterial cell.
Proteins are assembled on ribosomes.
So, option A. is correct.

In a food chain is simply a network of supply of energy beginning from the producer to the final consumer.
The correct options are
D Indirectly from the plant( science)
Energy Transfer in Food ChainSummary of the Energy Transfer
The flow of energy from the grasshopper to the bird is a direct flow, also the flow of energy from the plant to the grasshopper is a direct flow, this is so because there are not middle agent between the two organisms stated above.
When there is a middle agent, then the flow becomes and indirect flow.

Why is there more evaporation during the day and more condensation in the night?
Answer:
Wind moving over a water or land surface can also carry away water vapor, essentially drying the air, which leads to increased evaporation rates. So, sunny, hot, dry, windy conditions produce higher evaporation rates.

What's the primary difference between compressions on an adult vs. a small child?m
Answer:
Depending on the size of the child, you can use one or two hands to provide compressions. Because children have smaller chests than adults, the depth of compressions should be only one and a half inches. The compression and breath rate should be the same for children as for adults—30 compressions to two breaths.

This question is not complete below is the remaining part of the question. Is her hypothesis a true hypothesis or merely a prediction? (Has she provided rationale for her hypothesis?)
Do you think this is a good experimental design? Do you have suggestions for how she could improve her experimental design?
Answers:
The result of the experiment will determine if the hypothesis will be accepted or rejected and further explanation will be given to the effect.
Increase in dietry protein will subsequently increase the body weight as such the result show should tend towards a positive response to an increase in protein level.
The experiment design is completely randomized design(CRD) and it is good for the experiment to have the temperature all monitored and a close watch on the fishes.

Summarize what reasherchers did to improve the quality of post mining sites soil in
Answer:
The researcher centred on the potential uses of biochar, charcoal primarily used for agricultural and to improve the quality of post mining sites.
A method called mountaintop removal was used by mining firms. This means that they remove rock and mineral deposits off the top of the mountain to gain access to within the coal seams. The resulting soil is infertile and strongly acidic. The compacted soil after mine proves harder to bring seed into the soil.
The researchers try to use biochar to help reforest the soil at the post-mining site. Before it was reseeded and replanted, they got permission to add a layer of biochar to a post-mining site. the team created “planting cells” of biochar‐enhanced soil on the post‐mining site and that showed improvment in the sapling growth.
