Scientists are studying photosynthesis in a desert ecosystem that has plants, animals, and decomposers (which consume dead things). Which group or groups of organisms in the desert carry out photosynthesis?
Answer:
plants
Explanation:
photosynthesis can only occur in plants (producers), whille cellular respiration happens in everything (plants/producers, andimals/consumers, and decomposers)
therefore, the answer is plants
The group or groups of organisms in the desert that carry out photosynthesis is plants. The correct option is d.
What is photosynthesis?Cellular respiration occurs in all organisms, including plants, animals, and decomposers, yet only plants (producers) may engage in photosynthesis. Both eukaryotic and prokaryotic species possess the capacity for photosynthetic activity.
The stomata of desert plants are open at night. They take in CO2 at night, which is then transformed into acid and stored as an intermediate, and used for photosynthesis throughout the day (when the stomata are closed).
Other than the stem's presence of chlorophyll, everything else is the same. Autotrophs and heterotrophs are the two primary categories of organisms that utilize cellular respiration.
Therefore, the correct option is d, plants.

Write an explanation based on natural selection for the high incidence of tusklessness among female elephants in Gorongosa. Like all good scientific explanations, your explanation should include a claim, supporting evidence, and scientific reasoning to link the evidence to the claim. Use the Scientific Explanation of Evolution by Natural Selection chart
Answer:
Argument: A trend toward an increased incidence of tusklessness will result in decreased population sizes in the
future.
Claim: In the long term, tusklessness in African elephants is not beneficial to populations, even when heavy
poaching is occurring. So, as tusklessness increases, elephant population sizes will decline.
Evidence: Although poachers kill elephants with tusks, elephants rely on their tusks for survival. Elephants use
their tusks to strip bark off trees for food and to dig up water and minerals from the ground. Male elephants
also use their tusks in competitions with other males for females.
Reasoning: Tuskless elephants are probably not as healthy as those with tusks, as they cannot eat bark off trees
and are unable to dig for water and minerals. During harsh conditions such as droughts, elephants without
tusks would be less likely to survive. Male elephants without tusks are also more likely to be injured during
mating competitions. If too many males are injured or killed, there may be a decline in reproduction.
Over time, many of the tuskless elephants will die or be unable to reproduce, so the population’s size will
decrease.

What do you mean by ecosystem?An ecosystem consists of all the organisms and the physical environment with which they interact. These biotic and abiotic components are linked together through nutrient cycles and energy flows.
There are four basic components of an ecosystem: abiotic substances, producers, consumers, and reducers, which are also known as decomposers. Abiotic means that a substance is devoid of life, it is physical and not derived from living organisms.
Ecosystems are organized to better understand the frame of reference in which they are being studied. They are organized from smallest to largest; organism, population, community, ecosystem.

When a wave reaches a beach or coastline, it releases a burst of energy that generates a current, which runs parallel to the shoreline. This type of current is called a longshore current. The water in a longshore current flows up onto the beach, and back into the ocean, in a sheet formation. This action can cause significant beach erosion called A) ripping Eliminate B) parallel erosion C) longshore drift D) longshore rip
Answer:Longshore drift
Explanation:
Longshore drift which originates from longshore current is a geological process which involves the movement of sediments eg pebbles, sand along a coast in one direction which is determine by a prevailing wind, and so generates a water current which moves parallel to the shoreline at about 45 degrees.

Scientists have linked the human genome to a parts list. Explain what they mean. What other analogy (comparison) can you make?
Answer:
The pieces can be represented by genes
Explanation:
It has been shown that the human genome contains more than 30 thousand protein‐coding genes, as well as transposable elements, repetitive and non-coding RNA sequences. These protein-coding genes are in turn composed of coding regions (exons) separated by non-coding regions (introns). The analysis of the human genome enables the scientists to identify genes associated with specific signaling network pathways and diseases.

Why do some scientists think that global warming would increase the
strength of hurricanes?
A. Hurricanes could form in areas currently covered by glaciers.
B. Hurricanes rotate faster during summer months.
C. Hurricanes get their energy from the warmth of oceans.
D. Hurricanes would gain strength from heated landmasses
Answer:
C. Hurricanes get their energy from the warmth of oceans.
Explanation:
Global warming is defined as a gradual rise in the earth's temperature caused by the greenhouse effect caused by increased levels of carbon dioxide, CFCs, and other pollutants.
What are hurricanes?Hurricanes are massive storms with rotating wind speeds of 74 miles per hour. The rotating wind blows with terrifying force across the warm water of the tropics. This force washes ashore, causing destruction and even death. Hurricanes are known as one of nature's most destructive storms because of the damage they cause.
Thus, we can conclude that in option C, Hurricanes get their energy from the warmth of oceans because Hurricanes form over relatively warm sea surfaces, which has led to speculation that global warming will significantly increase hurricane activity.

Imagine if the population in your neighborhood suddenly doubled in size. This increase
would put a strain on transportation, food, and electricity. What steps might the
neighborhood take to relieve these problems? Are there any consequences to taking these
steps? Write your answer in one or two short paragraphs.
Answer:
An increase in population leads to more cars on the road. That could clog the roads. Adding extra lanes of traffic and roads could help address this problem. But roads cost a lot of money and might require clearing away valuable natural resources. More people also means the demand for food will increase. People will have to grow more crops, or cities will have to provide more ways to get groceries. Growing more crops and setting up grocery stores will cost money and use up land, just as adding roads does. A larger population also puts a strain on utilities, such as electricity. Increased demand may result in the depletion of fossil fuels, which can interfere with the fuel needs of future generations. Investments in clean energy could help limit this effect.

How does natural selection lead to evolution?
a
Environmental changes kill weaker members of the species.
b
Stronger offspring kill weaker members of the species.
c
Overproduction provides food for stronger members of the species.
d
Helpful traits accumulate among surviving members of the species
Answer:
The correct answer is option b. "Helpful variations accumulate among surviving members of the species".
Explanation:
Natural selection is the most accepted theory of evolution, described by Charles Darwin in 1859. This theory explains that by the survival of the fittest, the helpful variations accumulate among surviving members of the species. The variations or mutations that are not helpful for the species are lost by predators and environmental factors, while the helpful variations remain in the surviving members, which leads to the species evolving to have improved characteristics.

Answer:
animal-like protist
Explanation:
plato
Protozoans are classified as animal-like protists. Therefor, option (B) is correct.
What are protozoa?Protozoa are single-celled eukaryotic organisms that belong to the Kingdom Protista. They are typically found in water, soil, and as parasites in plants and animals. Protozoa are classified based on their method of movement, morphology, and mode of nutrition. Some protozoa are motile and use flagella, cilia or pseudopodia to move, while others are non-motile.
Protozoa are classified into four major groups: amoebae, ciliates, flagellates, and sporozoans. Amoebae move by extending pseudopodia or "false feet," which allows them to crawl and engulf food. Ciliates use hair-like projections called cilia for movement and have a distinctive micronucleus and macronucleus in their cell structure. Flagellates use whip-like flagella to move and are often found in aquatic environments. Sporozoans, on the other hand, do not have any means of independent movement and rely on a host to survive.
Some protozoa can cause diseases in humans and animals, such as malaria (caused by Plasmodium), sleeping sickness (caused by Trypanosoma), and amoebic dysentery (caused by Entamoeba histolytica). Despite their small size, protozoa play an essential role in the food chain as primary producers and decomposers.

What would the graph show?
A)
global temperature increasing as CO2 concentration increases
B)
global temperature increasing as CO2 concentration decreases
C)
global temperature decreasing as CO2 concentration increases
D)
global temperature stabilizing as CO2 concentration increases
Answer:
A)
global temperature increasing as CO2 concentration increases
Explanation:
Global warming is the progressive increase in the temperature of the earth's atmosphere. Global warming is caused by an increase in the concentration of greenhouse gases e.g CO2, chlorofluorocarbons etc. These greenhouse gases, in which carbondioxide is an important example, are capable of trapping heat in order to keep the earth warm.
Howeever, as the concentration of CO2 and other greenhouse gases increase in the atmosphere, the earth's atmospheric temperature also increases above normal, causing Global warming.
In this case, the science teacher's graph will show that global temperature is increasing as CO2 concentration increases.
