The correct answer is (d) It would have more carbon dioxide.
The green plants that is present in the environment utilizes the carbon dioxide present in the environment. This carbon dioxide is utilized in the process called photosynthesis, and as a result of that oxygen is released into the environment. If there would have lesser number of plants that carry out photosynthesis then the amount of carbon dioxide will increase in the atmosphere.

Which trilobite characteristic did not change through time? a. shape of eyes c. number of body segments b. 3-lobed body d. number of spines d. number of spines is a trilobite characteristic does not change through time.
The right answer is the lobed body.
The name trilobite comes from the subdivision of the body into three longitudinal lobes:
A medial lobe, the rachis,
And two lateral lobes, the pleura.
There is also a subdivision into three regions from front to back: the cephalon ("head"), the thorax and the pygidium ("tail").
The number of spines is a trilobite characteristic that did not change over time, unlike the shape of their eyes or the number of body segments.
Explanation:Trilobites are an extinct group of marine arachnomorph arthropods. They are recognized by their characteristic 3-lobed, 3-segmented body structure. Although trilobites underwent numerous changes over time due to evolution, one characteristic that did not change was the number of spines. The number of spines remained consistent throughout the trilobite's existence. This is in contrast to other trilobite characteristics such as the shape of their eyes or the number of body segments, both of which evolved over time in response to changing environmental conditions.

The diagram below represents two cells viewed using the same magnification with the same microscope.
One possible conclusion that can be drawn about the activity of these two cells is that
Based on the visible features, one possible conclusion is that Cell B is more active than Cell A. The correct option is B. more active transport occurs in cell A than cell B.
Based on the image you sent, here are some possible conclusions that can be drawn about the activity of the two cells:
Cell A:
Less active: The presence of a cell wall suggests Cell A is a plant cell. Plant cells typically have less metabolic activity compared to animal cells due to their slower growth rates and photosynthetic energy production.
Storing energy: The large central vacuole in Cell A could indicate storage of excess nutrients or waste products, suggesting lower metabolic activity compared to Cell B.
Cell B:
More active: The absence of a cell wall suggests Cell B is an animal cell. Animal cells are generally more metabolically active than plant cells due to their diverse functions and constant need for energy from external sources.
Engaged in protein synthesis: The prominent rough endoplasmic reticulum (RER) in Cell B indicates high protein production activity, suggesting a more active metabolic state compared to Cell A.

6. Answer;
- Faster
Explanation;
Compared to the time in Earth's history before humans appeared, rates of soil erosion are faster.
-Soil erosion is the wearing apart of topsoil. Topsoil is the top covering of soil and is the abundant fertile because it includes the several natural, nutrient-rich minerals. Every year, around 75 billion tons of soil is disintegrated from the land—a rate that is about 13–40 times as quick as the typical rate of erosion.
Additionally, some human activities associated with building structures increases the rate of erosion
7. Answer;
-Mass movement
The process responsible for moving material downslope under the influence of gravity is called mass movement.
Explanation;
-A mass movement is the geomorphic process through which soil, sand, regolith, and rock move downslope typically as a solid, continuous or discontinuous mass, largely under the force of gravity.
-It involves the sudden movement of a block of material along a flat, inclined surface is called a rock slide or a slide.
8. Answer;
The plant roots bind the soil and regolith together.
The removal of vegetation may trigger mass movements because the plant roots bind the soil and regolith together.
Explanation;
-Vegetation removal can trigger mass wasting or mass movement as vegetation stabilizes soil. When it is removed from a slope, the slope is vulnerable to water and wind erosion.
Mutagens such as pollutants and UV light can cause mutations in DNA to occur at a higher rate than normal. These mutations may be beneficial in some cases, but often they lead to cancer. Which of the following best describes how cancer cells affect the body? ...?
a. They cause the immune system to produce antibodies, which attack healthy cells along with the cancer cells.
b. They consume normal cells and use them as fuel to reproduce and attack more healthy cells.
c. They have an abnormally short cell cycle, and they die faster than the liver is able to remove them from the body.
d. They take nutrients needed by healthy cells, and as they grow they interfere with the function of normal cells and organs.
Correct answer: D). They take nutrients needed by healthy cells, and as they grow they interfere with the function of normal cells and organs.
Cancer is uncontrolled growth of the cell in the body. The Old cell does not die and instead of that, they have grown out of control, which results in the formation of new abnormal cells. These may form a mass of tissue called a tumor.
Due to uncontrolled growth of a cell, the normal function of neighboring tissue or organ may be disturbed or it might damage vital organ such as kidney, heart, lung etc and may cause death.
Answer:
d. They take nutrients needed by healthy cells, and as they grow they interfere with the function of normal cells and organs.
Explanation:
Cancer is the rapid production of cells. Many cancer cells have a defect in a gene called p53, which is responsible for delaying the cell cycle until all chromosomes are replicated. Mutations or damage to this gene make cells unable to respond to the signals that normally control their growth and division
Which of the following molecules get recycled during photosynthesis
When the light absorbs by the photosynthetic apparatus, the water molecules break down to produce essential material to continue the photosynthetic cycle as electron and H-ions. The H-ions becomes stored in thylakoid chamber and passed through the ATP synthetic machines to refill the ADP or AMP molecules. The generated electron passes through the various stages of photosynthetic series to finally produce the NADPH which also acts as energy transfer compound. At the PSI, the electron transfer to the NADP to generate NADPH.
What cell organelle controls the activities of the entire cell?
Nucleus is called the brain of the cell. Nucleus is the organelle which controls the activities of the cell.
The command center of eukaryotic cells is the nucleus. Additionally, it controls how genes and gene expression are coordinated in Chromosomes, nuclear membrane, nucleoplasm, and nucleolus make up the nucleus' structure. When compared to other cell organelles, which make up around 10% of the cell's volume, the nucleus is the most noticeable organelle. A eukaryotic cell typically possesses the one nucleus. Some eukaryotic cells are enucleate.
The first organelle to be identified or found was the nucleus. The nuclear envelope, which is a nuclear membrane, the nucleoplasm, the nucleolus, and the chromosomes make up the cell nucleus. The matrix found inside the nucleus is known as nucleoplasm, sometimes known as karyoplasm. The cytoplasm and the components of the nucleus are separated by the nuclear membrane.
Therefore, nucleus controls the cell and its activities.

Which of the following best describes integrated pest management?
A. The practice of using pesticides early in the growing season to minimize pest populations
B. The practice of using biological, cultural, environmental, and chemical means to control pests
C. The practice of using no synthetic fertilizers or pesticides to control pests
D. The practice of using only strong pesticides to control pests
Answer:
The correct answer for: Which of the following best describes integrated pest management? Is: B. The practice of using biological, cultural, environmental, and chemical means to control pests
Explanation:
To understand this answer we need to remember what IPM of integrating pest management is. IPM is the combination of biological, cultural, environmental and chemical means to minimize the local threat of pests in the crop or area of attention. First of all the objective is not to eradicate, exterminate or extinguish. But control them in other words, they will still be there but won't mean damage or danger to the crop or zone. Now, IPM seeks to do the least amount of damage to humans and the pests. So pesticides and fungicides are not welcomed in it. So, IPM is a whole strategy of changing the environment so that those pests won't mean an economical threat.

If a male has a disease that is Y-linked, what percentage of his sons will inherit the disease?
Final answer:
Sons will have a 100% chance of inheriting a Y-linked disease from their father because they receive their father's Y chromosome.
Explanation:
If a male has a Y-linked disease, each of his sons will inherit the Y chromosome that carries the disease gene. Since males only have one Y chromosome and they inherit it directly from their fathers, the probability that a son will inherit a Y-linked disease from his affected father is 100%. This differs from X-linked genetic disorders, where the chance of inheritance varies depending on the mother's genotype and the sex of the offspring.
What happens after pollen lands on the stigma of a flower? it grows a tube to travel down to the ovary.it fertilizes the plant at the stigma.it grows a tube to travel to the style.it grows a tube to travel to the petal.?
Answer: it grows a tube to travel down to the ovary
Explanation:
As a result of pollination, pollen grain lands on the sigma of the pistil or carpel. On the stigma pollen grain begins to germinate and grows a long pollen tube. The pollen tube grows longer and makes its way from the stigma, down the style and reaches to the ovary. Pollen tube carries two male gametes or sex cells. One male gamete fertilize the egg cell to produce zygote and the gamete fuses with polar nuclei to form primary endosperm cell.
