Explanation:
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.

Which statement describes the impact of ocean currents on climate?
Ocean currents create changes in the temperature of air over land masses.
Ocean currents cause the temperature of air over large bodies of water to change.
Ocean currents move cold water from the equator to the poles, creating cool weather regions.
Ocean currents carry warm water from the poles to the equator to create warm weather regions.

Ways
Answer:
2
Explanation:
An ocean current is defined as the continuous or permanent movement of sea water which is caused by different forces such as the coriolis effect, wind, temperature, breaking waves and salinity differences.
Ocean currents play important role in climate changes of large water bodies as they transport cold water to the tropics from the poles and precipitation and warm water from the equator back toward the poles. Ocean current restricts uneven distribution of sunlight reaching earth surface which influence the temperature of air above water bodies. If there will be no ocean currents, the temperature of water bodies will be very hot and very cold at poles.
Hence, the correct option is 2.
Answer:
Ocean currents cause the temperature of air over large bodies of water to change

What are 5 ways carbon dioxide is released into the environment?
What is the role of decomposers in the carbon/oxygen cycle?
How do humans impact the carbon/oxygen cycle
Answer:
Explanation:
*organisms respire or decompose (decay), carbonate rocks are weathered, forest fires occur, and volcanoes
*In terms of this cycle, the decomposers metabolize oxygen and release carbon dioxide. The primary producers then use these nutrients to fuel photosynthesis, which provides oxygen for the consumers
*burning fossil fuels, changing land use, and using limestone to make concrete all transfer significant quantities of carbon into the atmosphere.

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.

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.

Please someone help i will give you full ratings
Answer:
Hypothesis: the smell of decomposing apples may attract fruit flies more than the smell of decomposing bananas.
Experiment: two separated fruit fly populations with a sample size statistically significant (N: 500 or higher) must be grown in clean boxes. Subsequently, the fruit fly populations should be simultaneously released in a tube that connects the two boxes with other two boxes containing: -Box 1: apples in decomposition and -Box 2: bananas in decomposition. After one hour, the fruit boxes must be simultaneously closed and the fruit flies must be counted. Finally, it is necessary to apply a statistical index in order to calculate the significance between groups (i.e., fruit flies closed in both fruit boxes).
Positive control: fruit flies released and counted in boxes containing apples and bananas in normal conditions.
Negative control: fruit flies released and counted in clean boxes.
Theory: the scent of breaking down apples may draw in natural product flies more than the scent of breaking down bananas.
Experiment:
Two isolated natural product fly populaces with a test measure measurably critical (N: 500 or higher) must be developed in clean boxes.
Hence, the natural product fly populaces ought to be at the same time discharged in a tube that interfaces the two boxes with other two boxes containing: -Box 1: apples in deterioration and -Box 2: bananas in decay.
After one hour, the natural product boxes must be at the same time closed and the natural product flies must be checked.
Positive control: natural product flies discharged and tallied in boxes containing apples and bananas in ordinary conditions.
Negative control: natural product flies discharged and numbered in clean boxes.
Experimental DetailsExperimental information are collected through dynamic mediation by the analyst to create and degree alter or to make distinction when a variable is modified.

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.

Animals that eat plants get the energy stored in the plants and use it for things such as moving around. However, only a small fraction of the energy in the plants gets converted to useful energy for the animal. Most of the energy is lost to heat. How can this situation be used to support the idea of the law of conservation of energy?
A. A The amount of energy used by the animals, added to the amount of energy lost to heat, equals the amount of energy from the plants eaten by the animal.
B. B While some animals get their energy from plants, there are also many animals that get energy by eating other animals, and still other animals that eat both.
C. C All the energy lost to heat by animals provides the heat energy that plants need to live and grow, allowing them to make their own food.
D. D When plants and animals die, their energy goes into the soil, where growing plants can absorb it, turn it into food, then transfer this energy to animals.
Answer:
A. A The amount of energy used by the animals, added to the amount of energy lost to heat, equals the amount of energy from the plants eaten by the animal.
Explanation:
The law of conservation of energy states that "energy can neither be created nor destroyed but can only be changed from one form to another". This means that during the energy transfer cycle, energy cannot be created or destroyed by any process, however, it can only be changed from one form to another via the different processes undergone by living organisms.
This question describes how animals get food needed for their life processes by feeding on plants. However, they (animals) make use of only a little fraction (about 10%) of the total energy in plants they feed on, because most of the energy (about 90%) is lost as heat when the plant undergoes metabolic activities.
This situation describes the law of conservation of energy in the statement that "The amount of energy used by the animals, added to the amount of energy lost to heat, equals the amount of energy from the plants eaten by the animal" because it shows that energy cannot be created neither can it be lost, hence, the sum of the energy that was converted to heat energy by plants and the energy utilized by the animal will give the total amount of energy initially present in the plant before the animal fed on it.
Which of these DOES NOT affect the carrying capacity of an ecosystem?
1.variety of different food
2.total amount of food
3.competition for food
4.food being available over time
