In 1996, the comet Hale Bopp came close to Jupiter and its orbit around the sun changed from 4200 years to 2380 years. For scientists to understand the orbital changes in the comet Hale Bopp, first they must understand -
A) the composition of Jupiter
B) the magnetic attraction of objects
C) gravitational attraction of objects
D) the similarities of planets and comets
Answer:
C
Explanation:
Orbit is just the smaller object that's orbiting the bigger object is trying to move in a straight line but the gravitational force from the bigger object is trying to pull the smaller object to itself. I hope this answers your question!
Describe the differences and similarities between lecithin and cephalin. Match the words in the left column to the appropriate blanks in the sentences on the right. ResetHelp Lecithins and cephalins are both sphingolipids; they consist of glycerol with fatty acids forming bonds with the first and second groups. The third group of the forms a with phosphoric acid, which forms another bond with an amino alcohol. In lecithins, the amino alcohol is ; in cephalins, the amino alcohol is usually .
Answer:
Here, we have a composition passage and we are required to fill in the with missing words. The missing words are highlighted in bold format and underlined.
Lecithins and cephalins are both glycerophospholipids; they consist of glycerol with fatty acids forming ester bonds with the first and second hydroxyl groups. The third hydroxyl group of the glycerol forms a phosphate bond with phosphoric acid, which forms another phosphate bond with an amino alcohol. In lecithins, the amino alcohol is choline; in cephalins, the amino alcohol is usually ethanolamine.
Explanation:
Lecithin is a chemical complex composed primarily of fatty acids, glycerol, phosphoric acid, and choline. It can be present in egg yolks, soybeans, sunflower seeds, and plant seed cells and is completely normal. Soybean and sunflower lecithins contain much more important fatty acids than rapeseed lecithin, making them nutritionally more useful.
Phosphatidylethanolamine, also known as cephalin, is a phosphoglyceride that, like phosphatidylcholines and lecithins, is a component of biological membranes. A glycerol residue esterified by two fatty acids and a phosphoethanolamine residue gives rise to phosphatidylethanolamines. They're made by combining CDP-ethanolamine with diglycerides and releasing a CMP molecule. Phosphatidylcholines are formed when S-adenosylmethionine methylates the amine in ethanolamines. They're mostly found in the inner layer of plasma membranes' lipid bilayers.
Natural selection will only lead to evolution if it allows for an organism to ________.
a. possess advantageous traits.
b. compete for resources.
c. produce offspring.
d. all of the above.
Answer:
b
Explanation:
Natural selection will only lead to evolution if it allows for an organism to process traits, compete for resources and produce offspring. The correct option is d.
What is natural selection?Natural selection is indeed an evolutionary mechanism. Lifeforms which are better adapted to their surroundings are much more likely to flourish and pass on the genetic traits that helped them thrive. Species change and diverge as a result of this process.
Natural selection, Darwin proposed, is a framework for evolution in which genetic variants that help support life, reproduce and survive as well as become more prevalent in a population over time.
Natural selection will occur if three conditions are met, according to Darwin's theory. These conditions, which are outlined as,
Represent a struggle for survival.Exhibit variation.Undergo inheritance.These are the conditions that are said to be both necessary and sufficient for natural selection.
Natural selection will only result in evolution if an organism is able to process traits, compete for resources, and produce offspring.
Thus, the correct option is d.

A) reduce environmental impacts
B) build and populate more zoos
C) pass more laws about land use
D) introduce new predators to an environment
Answer: 1. C) increased water temperature upstream. 2. D) introduce new predators to an environment. brainliest??
Explanation:
The change that is an environmental effect of building dams is increased water temperature upstream, which is in Option C, and humans can increase the rate of endangered or extinct species by reducing environmental impacts, which is in Option A.
What is Human activities on species?Human activities are the primary cause of species endangerment and extinction, so humans must take actions to reduce environmental impacts in order to increase the rate of endangered or extinct species, and by reducing hunting and poaching and restoring degraded ecosystems can help protect endangered species, and reducing carbon emissions and promoting sustainable development can help mitigate the effects of climate change.
Hence, the effect of building dams is increased water temperature upstream, which is Option C, and humans can increase the rate of endangered or extinct species by reducing environmental impacts, which is Option A.

O Infant Respiratory Distress Syndrome occurs when there is a lack of surfactant
produced. THis is common in premature infants.
In healthy individuals, friction is a major factor affecting pulmonary ventilation
Answer: Infant Respiratory Distress Syndrome occurs when there is a lack of surfactant produced. This is common in premature infants.
Explanation:
Respiratory distress syndrome (RDS) is a well-known breathing disorder that is common in premature infants. It happens when there is a lack of surfactant produced in the baby's lungs which is quite bad because surfactant enables babies to breathe when they are born by keeping the lungs expanded.
It is common in premature infants because the lungs only begin to produce surfactant in the third trimester so babies that are born prematurely did not get to produce sufficient quantities. If not treated immediately, brain damage could follow.
Anoles are a family of IIzards found throughout the Americas. Green anoles, Anolis carolinensis, are native to i specific area of Florida. In this
area, the primary territory of green anoles was once along the ground and in low-level branches. However, the Introduction of brown anoles,
Anolis sagrei, from Cuba forced green anoles to shift o their territory to the tops of trees. The branches at the treetops are smoother and thinner
than those close to the ground. Over time, the toe pads of the green anoles have become larger and stickler.
What is the best explanation for the change In green anoles' toe pads?
Some individuals In the green anole population had mutations that helped them survive and reproduce In the new conditions,
so thelr genes were passed on to the next generation.
O B. Gene flow between the green and brown anoles provided the green anoles with traits that helped them survive and
reproduce, and those tralts were passed on to the next generation.
The feet of the green anoles became larger and stickler as they used them, which helped the green anoles to better survive,
reproduce, and pass the tralt on to the next generation.
