Answer:
Slime molds are example of protists that can produce energy
Explanation:
Slime molds are known as photosynthetic protist. They can produce their own foods. Like plants, slime molds also have cellulose in the cell walls of their spores. They are unicellular but they can form colonies.
Hence, it can be said that Slime molds are example of protists that can produce energy
why are manure better than fertilizers
Manure is better than fertiliser. Manure is derived naturally and adds a lot more than just nutrients to the soil. They increase the activity of the microbes in the soil and increase its fertility. On the other hand, fertilisers harm these microbes and cause health issues in the consumers since they are synthesised chemically.

4. The peppered moth lives on the trunks of trees in England. There are two colorations of this moth, light and dark, and both
are eaten by birds. A study found that prior to the Industrial Revolution, the number of light-colored moths found on the
trunks of trees was far greater than the number of dark colored moths. However, after the industrial Revolution, the numbers
were reversed
How would the genetic variation of the moths account for the change in the population sizes of each color? 50.7L152
A. The dark moths were able to kill off many of the light-colored moths, so their numbers increased a lot.
B. Natural selection caused the light species of moth to change into the dark species, allowing them to be better
hidden
C. After the industrial Revolution started, the light colored moths left the area to go live in another, less populated
environment
D. Natural selection favored the dark-colored moths because the factories were producing soot that landed on the
trunks of the trees.
Answer:
D.
I remember doing a question like this in class while learning about natural selection. The 2 colorations of moth live in a habitat that originally supported the lighter variant due to the light-colored trees. When the industrial revolution began, the soot levels reversed this because the black moths were more camouflaged that the lighter ones. A way we could prove this was the amount of black dresses and dark colored clothing during the time, often due to the fact that lighter colored clothing would turn black by the time the wearer arrived home. The lighter colored moths simply died off a bit because of this.

How are sedimentary rocks made. A. Magma or lava is cooled B. Materials are pressed together C. Chemical reactions change minerals. D. Earthquakes causes small pieces to fall
Answer:
B. Materials are pressed together
Explanation:
sedimentary rocks are made up of pieces (clasts) of pre-existing rocks. Pieces of rock are loosened by weathering, then transported to some basin or depression where sediment is trapped. If the sediment is buried deeply, it becomes compacted and cemented, forming sedimentary rock.
Sedimentary rocks are made up by the pressing down together the materials which are loosened through weathering. Thus, the correct option is B.
What are Sedimentary rocks?Sedimentary rocks are the type of rock which are formed by the accumulation or deposition of mineral particles or organic particles at the Earth's surface, followed by cementation of the particles.
Pieces of rock are loosened by weathering of particles, then these are transported to basin or depression where the sediment is trapped. If the sediment is buried deeply in the basin, it becomes compacted and cemented to form sedimentary rocks. Clastic sedimentary rocks may have particles of rocks ranging in size from microscopic clay to huge boulders.
Therefore, the correct option is B.

Overtime organisms change sometimes they change so much of the sentence may be completely different for their ancestors what must happen for this process to occur
Answer:
In order to survive in the changing environmental conditions.
Explanation:
Changes occur in the body of an organism which make them different from their ancestors because these organisms evolve with the passage of time due to difference in environmental conditions. If these organisms can't evolve, they can't tolerate that environment and climatic condition and also become extinct so this process occur in the organisms in order to survive that different environmental conditions so we can say that this change is necessary in the organisms to survive.

1. which model best shows the prediction of growth for a population when taking into account the carrying capacity of its environment?
a. logistics model of growth
b. capacity model of growth
c. mathematical model of growth
d. exponential model of growth
2. which of these contribute to the carrying capacity of a population?
a. environmental conditions
b. density-independent factors
c. weather conditions
d. density-dependent conditions
3. which of these limit population growth?
a. density-dependent factors
b. all limiting factors
c. density-independent factors
d. environmental factors
4. which of the following is a density-dependent factor?
a. hurricane
b. water availability
c. warm weather
d. forest fire
Answer: 1. a. logistics model of growth
2. a. environmental conditions
3. b. all limiting factors
4. b. water availability
Explanation:
1. a. logistic model of growth will show the increase in population of a species in accordance with the carrying capacity exponentially but when the population will experience the scarcity of resources it will decline considerably.
Carrying capacity is the total number of members of the population of a species that an ecosystem can sustain by providing resources.
2. b. All environmental conditions which favor the survival of the living beings will contribute to the carrying capacity for example food, water, shelter, and other resources.
3. b. Limiting factor is the one which limit the chances of survival and growth of a particular species in an ecosystem. For example, scarcity of food, here food is the limiting factor.
4. d. A density dependent limiting factor is the one which affects the population of the species based upon the density. The water availability is a density dependent limiting factor because the more the density or abundance of a population more will be the scarcity of water as it will be required by all organisms. So, the species population may experience decline due scarcity of water.
Which adaptation below is a structural adaptation? A. Lions care for their young. B. Zebras form a herd and watch for predators. C. A bird builds a nest. D. A deer has flat teeth for chewing plants.
Answer:
D. A deer has flat teeth for chewing plants.
Explanation:
Adaptation, which is the ability of an organism to survive changes in its natural environment, can either be structural, behavioral and physiological. Structural adaptation is the possession of a physical or structural feature by an organism to enable it survive or adjust to change.
According to this question, the FLAT TEETH possessed by the deer for chewing plants is an example of structural adaptation because the deer posseses a structural feature (flat teeth) that allows it to feed on plants for survival.

Why do earthquakes occur near the San Andreas fault?
A
One plate slowly pushes the other plate up.
B) A trench is created as one plate slides under the other plate.
Portions of the plates get stuck and then suddenly loosen and move.
D
One plate pushes hard enough to reverse the motion of the other plate.
Answer:
C.
Explanation:
Basically a faster explanation is the san andreas fault is a transform boundary. If you have an oreo break one of the top pieces and slide them slowly it will get stuck causing an earthquake.
Earthquakes occur near the San Andreas fault because portions of the plates get stuck and then suddenly loosen and move. Hence option C is correct.
What is earthquake?Earthquake is defined as the abrupt release of energy in the Earth's lithosphere that causes seismic waves and causes shaking of the planet's surface. Earthquakes typically result from subsurface rock breaking unexpectedly and rapid movement along a fault. The seismic waves that cause the ground to tremble are brought on by this quick release of energy.
According to new University of Southern California research that contributes to the understanding of how earthquakes occur, tremors along a notorious section of California's San Andreas Fault seem to be fueled by thermal instability brought on by frictional shear occurring much deeper in the Earth than previously thought.
Thus, earthquakes occur near the San Andreas fault because portions of the plates get stuck and then suddenly loosen and move. Hence option C is correct.

Is a meander predominantly formed by erosion or deposition?
Answer:
Meanders change position by eroding sideways and slightly downstream. ... Thus by eroding its outer bank and depositing material along its inner bank, a stream moves sideways without changing its channel size.

2. What is the change (mutation) in DNA?
Answer:
A mutation is a change in a genetic sequence. Mutations include changes as small as the substitution of a single DNA building block, or nucleotide base, with another nucleotide base. Meanwhile, larger mutations can affect many genes on a chromosome. Along with substitutions, mutations can also be caused by insertions, deletions, or duplications of DNA sequences.
Explanation:
Some mutations are hereditary because they are passed down to an offspring from a parent carrying a mutation through the germ line, meaning through an egg or sperm cell carrying the mutation. There are also nonhereditary mutations that occur in cells outside of the germ line, which are called somatic mutations. Mutations can be introduced due to mistakes made during DNA replication or due to exposure to mutagens, which are chemical and environmental agents that can introduce mutations in the DNA sequence, such as ultraviolet light. Some mutations do not result in changes in the amino acid sequence of the encoded protein and can be described as silent mutations. Other mutations result in abnormal protein products. Mutations can introduce new alleles into a population of organisms and increase the population's genetic variation.
Explain how the respiratory system and circulatory system cooperate to provide the body’s cells with a constant supply of oxygen.
Answer:
In the respiratory system, you inhale oxygen which is transferred to the blood in the alveoli and circulated throughout the body. The blood in the circulatory system has a protein called hemoglobin which binds to the oxygen and carries it throughout the body. This oxygen is then given to the different cells for cellular respiration. It then carries the waste products (CO2) of cellular respiration back to the lungs and it is exhaled out.
Errors that occur during meiosis are present in all cells of the body, whereas errors that occur during mitosis may occur in only a small number of cells.
Answer:
Due to difference in their presence in the body.
Explanation:
Errors that occur during meiosis are present in all cells of the body because meiosis cell division occurs in the sex cells of an organisms so that the errors are effects all the cells of that organism, while on the other hand, errors that occur during mitosis may occur in only a small number of cells because mitosis cell division occurs in the somatic cells so the errors are present in some body cells so we can conclude this errors in meiosis affect all cells whereas errors in mitosis affect less number of cells.
