from a particular location on earth, why can we see many more total eclipses of the moon that the total eclipses of the sun?
Answer:
Hiii! I'm here to help!
Explanation:
The Moon is always in the same place in our sky while the Sun moves around the sky. The Moon is much bigger in the sky than the Sun. The line-up of the Earth Moon and Sun needed for a lunar eclipse happens many many times more often than what is needed for a solar eclipse. A total lunar eclipse is visible over a much larger part of the Earth's surface than a total solar eclipse.

What are 5 different types of heterotrophs, what do they eat, and give an example of an organism for each category.
Answer:
Five different types of heterotrophs are carnivores, herbivores, omnivores, scavengers, and detritivores.
Carnivores eat the meat of other animals. Example: Bear
Herbivores eat vegetation. Example: Deer
Omnivores eat a combination of both meat and vegetation. Example: Humans
Scavengers eat things left behind by carnivores and herbivores. Example: Raccoon
Detritivores eat small bits of organic matter, such as soil. Example: Worms
Edit: If you'd rather substitute one of those for a decomposer, Decomposers break down dead or decaying organisms. Example: Mushroom, or fungi.

How does competition limit the dispersal of organisms? *
Answer:
Three factors that limit dispersal of a species are physical barriers, competition, and climate. Physical Barriers include water, mountains, deserts, and canyons because these barriers are hard for most organisms to cross, they limit the movement of organisms.
If an animal has to pass through another animals territory to disperse, that animal may be killed or injured in the process, so it may opt not to move or not to move as far as it should.

Which statement BEST describes the effect of human urbanization on biodiversity in the Amazon
rainforest?
A
Human urbanization increases biodiversity because cleared land attracts more
species into an area
B
Human urbanization decreases biodiversity because habitats and resources are
lost to native species
С
Human urbanization increases biodiversity because of non-native species
introduced to the food web.
D
Human urbanization decreases biodiversity because limiting factors of the forest
ecosystem are reduced.
Human urbanization would generally decrease the biodiversity of any forest because habitats and resources are lost during the process of urbanization.
Urbanization refers to the process through which cities are created out of urban areas.Cities are created by removing vegetation and erecting infrastructures such as buildings, roads, bridges, etc. The removal of vegetation means that habitats of organisms would be lost as well as the biodiversity that constitutes the vegetation itself.Thus, urbanization would automatically lead to a loss of biodiversity in the Amazon forest.

Answer:
first one is chromosome and second one is double helix
Explanation:
idek if that's what your asking lol hope you do good
First image is the double helix and the second one is chromosome.
What are chromosomes?A chromosome is a long DNA molecule with part or all of the genetic material of an organism. In most chromosomes the very long thin DNA fibers are coated with packaging proteins; in eukaryotic cells the most important of these proteins are the histones.
Chromosomes allow DNA to be accurately copied during these cell divisions. So one more time. Chromosomes are found in the nuclei of our cells and allow DNA to be accurately copied during cell division.
Chromosomes are arranged in ordered haploid sets around the centre of the metaphase plate at mitosis in several grass species and hybrids.

Whales, birds, snakes, and fish need oxygen to survive. Even though they share this trait, these animals are not related because they do NOT —
A. inherit genetic instructions passed down from the same parents.
B. lives in the same type of environment.
C. eat the same types of food.
D. need oxygen to survive in their environments.
Answer:
A. inherit genetic instructions passed down from the same parents.
These animals are not related because they do not inherit genetic instructions passed down from the same parents. The correct option is A.
What is inheritance?The transmission of traits and otherwise information through one generation of individuals or cells to the next is referred to as inheritance.
Inheritance can occur through one of two mechanisms: genetic inheritance or epigenetic inheritance.
Deoxyribonucleic acid is another name for DNA. It is the genetic structure that is in charge of storing information.
A nitrogen base, sugar, and phosphate backbone make up DNA. Inheritance occurs when genetic information is passed from a parent to a child, and thus from one generation to the next.
A gene pair's two alleles are inherited, one from each parent. Alleles interact with one another in various ways. These are referred to as inheritance patterns.
Thus, the correct option is A.

Choose one of the water management concerns listed below and give an example of where this is happening. Please cite your source and change the heading of your post to show which concern you are discussing. Make sure to also show how this impacts the water cycle.
a. withdrawing large quantities from streams, lakes, and aquifers.
b. increasing runoff by clearing vegetation from the land.
c. altering weather patterns by clearing vegetation.
d. increasing flooding by disturbing natural flood controls.
Answer:
Water Withdrawal: it has happened in some lakes in Minnesota
Explanation:
The water cycle is influenced by seasonal-climatic fluctuations and human activity. Water withdrawal is one of the human activities that most seriously affect the amount of water in lakes and aquifers by reducing water storage, thereby altering the flow in streams, lakes and wetlands. Concerning this situation, the state of Minnesota incorporated 1- the use of a US database (State Water Use Database, SWUD) with useful water use information on withdrawals and consumptive uses and 2- an index based on the sum of permitted water withdrawal from surface and groundwater. This index estimates the use of water as a percent of the surface water runoff to define and predict the vulnerability of lakes, using data from 54 stream gages recorded from 1988-2007. The catchment scores are scaled from 0 to 100 depending on the percent of runoff used.

In hummingbirds feather color is incompletely dominant. A rather large population of hummingbirds has 396 red-sided individuals (RR), 257 brown sided individuals (Re) and 557 tan-sided individuals orr). Calculate the following:_______.
a. What is the allele frequency of the Rallele (o)?
b. What is the allele frequency of the rallele (a)?
Migration season comes and 200 of the red-sided individuals leave the nosulation before mating occurs.
c. After migration season what is the new allele frequency of the Rallele (0)?
d. After migration season, what is the new allele frequency of the rallelelo?
e. Which mechanism of evolution (natural selection, genetic drift, or gene flow) caused the allele frequencies to change?
Answer:
a) Frequency of the R allele: [(396 x 2) + 257] / (396 x 2) + (257 x 2) + (557 x 2) = 1049 / 2420 = 0.433
b) Frequency of the r allele: [(557 x 2) + 257] / (396 x 2) + (257 x 2) + (557 x 2) = 1371 / 2420 = 0.567
c) Frequency of the R allele: [(196 x 2) + 257] / (196 x 2) + (257 x 2) + (557 x 2) = 649 / 2020 = 0.321
d) Frequency of the r allele: [(557 x 2) + 257] / (196 x 2) + (257 x 2) + (557 x 2) = 1371 / 2020 = 0.679
e) migration is gene flow
Explanation:
Gene flow (also referred to as gene migration) is the movement of genes that acts to change allele frequencies in local populations by transferring genetic material from one population to another. Gene flow may be caused either by the movement of organisms that reproduce in new populations (migration), or by the movement of gametes (for example, pollen dispersal in plants).
How do bones grow (explain the process)?
