Explanation:
NASA scientists use satellites to monitor two important factors that lead too landslides
Answer:
The most important factors that lead to landslides are the declivity of the terrain and the type of soil.
Explanation:
Stony soils are more prone to landslides, especially on steep terrain and without any type of vegetation cover. During heavy rainfall, these two factors can promote landslides that cause major disasters, as water is able to drag this soil violently. To prevent this from happening and people from being harmed, NASA has developed satellites, which capture rainfall data and monitor the slope and composition of soils, being able to see in advance areas that could be landslides. In this way, it is possible to develop strategies that prevent the landslide from happening.

An oil mining company has started drilling oil offshore at a location. Thus far, it has benefitted the people by increasing employment opportunities in the area. Predict the most likely outcome the oil mine will have on the environment?
It will cause drying up of water in plants.
It will emit radiation which destroys plants.
It will produce greenhouse gases which pollutes soil.
It will contaminate the soil and water in the ocean.
Answer:
It will contaminate the soil and water in the ocean.
Explanation:
This is because the oil drilling will cause oil spillage on the soil and water in the ocean. The oil spillage will cover the oil and it will not allow plant to grow there. Any crops planted there will not grow because it had release chemical and act as covering which cannot support plant growth. When it is washed into the ocean or water bodies, it can lead to death if aquatic live because it will affect the amount of oxygen that will available to them.
Answer:
It will contaminate the soil and water in the ocean.

A population of squirrels eats acorns from local oak trees. In some years, oak trees produce much greater
numbers of acorns than usual.
Which of the following is the most direct effect of an increase of acorns on the squirrel population?
Answers
A The population has fewer predators.
B The population size increases.
C The population expands its territory into new habitats.
D The population size decrease due to competition.
Answer:
B
Explanation:
The population size increases
A population of squirrels eats acorns from local oak trees. In some years, oak trees produce much greater numbers of acorns than usual. The most direct effect of an increase in acorns on the squirrel population would be: the population size would increase, which is option B.
When there is an abundance of acorns, the squirrel population can benefit from a readily available food source. With more food available, squirrels are better able to meet their nutritional needs and reproduce successfully. This leads to an increase in the population size as more squirrels are born and survive due to the abundance of resources.

A grasshopper is an arthropod. Based on the grasshopper’s characteristics, which other animal likely belongs to this group?(1 point)
The grasshoppers are a group of insects that belong to the Califera suborder. The grasshoppers are arthropods. Another animal that shares similar characteristics to a grasshopper and belongs to this group is the crayfish.
What are the characteristics of grasshoppers?Grasshoppers are plant eaters and over time they may become pests for various cereal crops and vegetables. They are herbivores insects with hind legs that are very powerful.
Like other insects, grasshoppers breathe through tiny holes called spiracles that connect to trachea tubes. The air is carried through the grasshoppers' bodies by smaller tracheoles that branch off from the larger trachea tubes. The grasshopper breathes air through its body with every movement. Grasshoppers don't have lungs.

Know how to calculate the amount of chromosomes in mitotic cells and in gamete cells, when given an amount of the chromosome number for one of the two types of cells. For example, a fruit fly has 8 chromosomes or 4 pairs of chromosomes in its wing cells, how many chromosomes will be in each egg cell?
Answer:
4 chromosomes
Explanation:
Meiosis is a kind of cell division that produces daughter cells that already have their chromosome number reduced by half. Due to this reason, meiosis is called a reduction division. A diploid parent cell (2n) will produce gametes with haploid cells (n).
According to this question, a fruit fly has 8 chromosomes or 4 pairs of chromosomes in its wing cells, after undergoing meiotic division, it will possess 4 chromosomes in each gamete cell. Note that the chromosome number has been reduced by half.

Walking sticks are insects that may have either a striped body or a body without stripes. In one region where these walking sticks live, the vegetation is a plant with needle-like leaves that resemble the walking stick’s striped body. According to natural selection, what would most likely result from an increase in walking stick predators in the region? (SC.7.L.15.2) A.walking sticks without stripes will reproduce faster B.walking sticks with stripes will become more common C.walking sticks will develop a new, spotted pattern for their bodies D.walking sticks will live on rare plant species rather than the dominant species
Answer:
B. Walking sticks with stripes will become more common.
Explanation:
The striped bodies of the walking sticks will help them camouflage in the plants. The predators will be more likely to kill off the unstriped walking sticks, leaving the striped walking sticks to grow in population and become more common.

Compare and contrast negative and positive feedback loops. Which one is more common? Why?
Answer:
Negative Feedback LoopsA negative feedback mechanism or loop is a pathway stimulated by the deviation in the output, which causes changes in output to the direction opposite to the initial deviation.The negative feedback mechanism moves the variable factors towards the stable state or homeostasis after the control unit interprets the extent of the deviation.Negative feedback loops are more common than positive ones as they tend to stabilize the system.The loop detects the change in output and acts in the opposite direction to nullify the stimulus causing the change.These loops are activated under two conditions; when the value of the variable is above the normal value and has to be brought down and when the value of the variable is below the normal values and has to be brought up.Negative feedback mechanisms occur as a part of homeostasis to bring the variables back to their normal levels by counteracting the stimulus, causing the deviation in the first place.Like in a positive feedback mechanism, a negative feedback mechanism also contains different components that together help to maintain a stable state.Examples of Negative Feedback Mechanism
1. Regulation of blood glucose level
2. Temperature regulation
Positive Feedback LoopA positive feedback mechanism, as the name suggests, is a pathway that in response to a deviation in the output causes the output to change even more in the direction of the initial deviation.A positive feedback mechanism amplifies the deviations and brings state changes to the output.Positive feedback mechanisms are far less common than negative feedback mechanisms as it moves the body away from homeostasis.The process of positive feedback mechanism progressively amplifies the response as long as the stimulus is continued.The positive feedback loop can consist of either a single component that activates its own activity or several components with direct and indirect interactions.Positive feedback loops in biological processes are often observed in processes that need to occur quickly and towards completion as the output tends to increase the effect of the stimulus.Positive mechanisms are very few within living systems like the human body, but these can also be observed in the ecosystem, like in the case of ripening of fruit.Examples of Positive Feedback Mechanism
1. Menstrual cycle
2. Childbirth
Negative feedback loops are more common than positive ones as they tend to stabilize the system.
Positive Feedback vs Negative Feedback (8 Key Differences)Definition
The positive feedback mechanism is a pathway that in response to a deviation in the output causes the output to change even more in the direction of the initial deviation. A negative feedback mechanism or loop is a pathway stimulated by the deviation in the output, which causes changes in output to the direction opposite to the initial deviation.Effect on the homeostasis
A positive feedback mechanism breaks down the homeostasis system of the body. A negative feedback mechanism works to maintain the conditions of homeostasis in the body.Occurrence
The positive feedback mechanism is less common and occurs in specific situations.The negative feedback mechanism is more common and occurs in different organs and systems in the body.Stability
The positive feedback mechanism is less stable.The negative feedback mechanism is more stable.Effect
In a system with a positive feedback mechanism, the effective input is increased by the addition of actual input with the feedback signal.In a system with a negative feedback mechanism, the effective input is decreased as the feedback signal inhibits the actual input.External interruption
A positive feedback mechanism might require an external interruption.A negative feedback mechanism doesn’t require an external interruption.Changes
Positive loops enhances the change in physiological factors.Negative loops resists changes in physiological factors.Examples
Positive feedback mechanism in nature is observed during childbirth in humans and during the ripening of fruits. The negative feedback mechanism is observed during thermoregulation and maintaining the blood glucose level.does anyone know any of these answers??!

Track the evolutionary path of a butterfly and comment on it.
Answer:
The colorful canvas of the butterfly wing is an example of evolutionary innovation and adaptation. Compared with their ansestors, whose wings wore patterns of black, brown, and gray, the Lepidoptera (butterflies and moths) evolved a more varied palette of pigmentation.
I think it is very cool that they were able to evolve. For example, some butterflies use their bright colors to trick preators into thinking they are poisonous. The early butterflies could not do this.
Explanation:
Please brainliest!
Based on scientific information, the evolutionary path of a butterfly is primarily based on the origin of its species to eukaryotes and then to bilateria.
What is an evolution?An evolution refers to a biological and physical process that involves a gradual change in the characteristics and genetic make-up of the various species of organisms over several generations.
Based on scientific information, the evolutionary path of a butterfly is primarily based on the origin of its species to eukaryotes and then to bilateria such as:
Mid Eocene epochMid-CretaceousMothButterfly is a species of living organism with various characteristics and genetic make-up that have been in existence for about 60 million years.
