How does rising CO2 affect the different spheres?
Answers
Answer: air temperatures go up, and more water vapor evaporates into the atmosphere
Explanation: Carbon dioxide causes about 20 percent of Earth's greenhouse effect; water vapor accounts for about 50 percent; and clouds account for 25 percent. ... Likewise, when carbon dioxide concentrations rise, air temperatures go up, and more water vapor evaporates into the atmosphere—which then amplifies greenhouse heating.

Q3.) c
Explanation:
1. A farmer who is growing crops will need to water his crops regularly because of intraspecific competition. Intraspecific competition refers to the competition that occurs among the members of the same species.
The corn compete with each other for water, and hence, the farmer needs to water them regularly to meet their water requirement.
Hence, the correct answer is option C.
2. There are two growth models of population, namely logistic growth model and exponential growth model.
The logistic growth model shows intrinsic growth rate as it represents conditions that occur in the natural populations.
Hence, the correct answer is option B.
3. The offspring of a species that is randomly subjected to predation will like show a survivorship curve that will be similar to the one show in graphs 2 and 3.
hence, the correct answer is option C.

possible reasons for differences in enzyme activity
Answers
There can be several reasons for differences in enzyme activity, including temperature, pH, enzyme concentration, substrate concentration, and the presence of inhibitors or activators.
Enzymes are biological catalysts that accelerate chemical reactions in the body. The rate of enzyme activity can be affected by various factors, such as temperature and pH. Each enzyme has an optimal temperature and pH range at which it functions best. Deviations from this range can cause the enzyme to denature or lose its shape, leading to a decrease in activity.
Changes in enzyme concentration can also affect activity. An increase in enzyme concentration generally leads to an increase in activity, while a decrease in concentration leads to a decrease in activity. The rate of enzyme activity can also be affected by substrate concentration.

How are all organisms with similar physical characteristics related to one another?
Answers
Answer:
All organisms with similar physical characteristics are believed to be related through a common ancestor. This means that they share a similar genetic makeup that makes them look and behave in a similar way. For example, all mammals share common physical characteristics such as mammary glands and hair, which suggests that they are all descendants of a common ancestor that had these traits. Similarly, all birds have feathers and lay eggs, which suggests that they are all descended from a common ancestor that had these traits. This theory of common descent is supported by the study of genetics, fossil records, and comparative anatomy, and is widely accepted by the scientific community as the best explanation for the diversity of life on Earth.

Explain the relationship between each pair:Cellular Energy & Carbohydrate
Answers
Animals and other organisms obtain the energy available in carbohydrates through the process of cellular respiration.
When we say cellular respiration it is a set of metabolic reactions and processes that take place in the cells of organisms to convert chemical energy from oxygen molecules or nutrients into adenosine triphosphate (ATP), and then release waste products.
The relationship between these two is that cells take the carbohydrates into their cytoplasm, and through a complex series of metabolic processes, they break down the carbohydrates and release the energy (cellular energy).

A group of researchers transformed E. coli to express
dsRNA that matched a transcription factor, eaf-1. They
then fed these E. coli to C. elegans worms. When the
researchers examined the C. elegans, they found that
they had fewer offspring and were smaller individuals,
with similar characteristics to C. elegans in which eaf-1
had been knocked out.
The students suggested several hypotheses based on
these observations about how RNAi worked:
1. The dsRNA inhibited gene transcription.
2. The dsRNA inhibited mRNA processing.
3. The dsRNA inhibited translation of mRNA into protein.
4. The dsRNA inhibited protein folding.
Mark this and return
The researchers then performed a series of experiments
to determine which hypothesis was correct. The C.
elegans were found to be transcribing eaf-1 into mRNA,
but not producing eaf-1 protein. When the students
directly injected C. elegans with dsRNA and tracked
tagged mRNA, they found the mature mRNA was
degraded in the cytoplasm, and ribosomes were not
binding to it. Which hypothesis is supported by these
observations?
Answers
The hypothesis that is supported by these observations is that the dsRNA inhibited the translation of mRNA into protein (third option).
What does the experiment reveal about dsRNA?In this experiment, the C. elegans worms were transcribing eaf-1 into mRNA but not producing the eaf-1 protein. This phenomenon shows that dsRNA inhibited the translation of mRNA into protein related to the action of E. coli on the worms.
This also explains why the worms affected by this bacteria had fewer offspring and the offspring were smaller.

Consider the model and the experiment with the leaves. Can a fossil be created in a few weeks? How long
do you think it takes a dinosaur fossil to form?
Answers
Answer:
If other conditions are ideal, fossilization might happen faster quickly the more minerals that are present. The rate of this will also be greatly influenced by the size of the organism; small organisms, such as eggs or embryos, can actually fossilize very quickly. Possibly within a few weeks or months.
Petrified trees or dinosaur bones are examples of macrofossils. Once preserved remains have aged 10,000 years or more, they are considered fossils.

Answer:
The result of cross two squashes with yellow seeds is an offspring of squash with green seeds -dominant caracter- heterozygous and yellow seeds squashes in a genotype proportion 1:2:1 and phenotype proportion 3:1
Explanation:
The cross of two heterozygous individuals for a characteristic results in an offspring that will have both characteristics in pure and heterozygous form. It is a cross monohybrid which complies with the principle of independent segregation exposed by Mendel.
For the characteristic "seed color" the green color would be G and yellow represented as g.
