How do wetlands form?
Tributaries flow into rivers.
Runoff travels down the side of a divide.
Water builds up in a depression left by an ice sheet.
Groundwater comes to the surface and floods the land.
Answer:
D) groundwater comes to the surface and floods the land
Explanation:
Groundwater like water from river or lake comes to a land and before it has a chance to go back into the soil or evaporate, more water comes and floods the areas, thus the previous water stays and new water stays as well. If this cycle is repeated, a wetland will form.
wetlands form The tributaries flow into rivers.
How do wetlands form?Wetlands is a flat area of abundant herbaceous and/or shrubby vegetation that remains flooded most of the time. Swamps generally appear in areas where water flow is slow. In this way, the organic mass present in the waters decomposes on the spot.
With this information, we can conclude that wetlands are formed. The tributaries flow into rivers.

how is volume meausred
Answer: Volume is measured in cubic meters or cm
Explanation: In the International System of Units (SI), the standard unit of volume is the cubic meter (m3). The metric system also includes the liter (L) as a unit of volume, where one liter is the volume of a 10-centimeter cube. Thus 1 liter = (10 cm)3 = 1000 cubic centimeters = 0.001 cubic meters, so.
Answer:
Volume can be measured in many ways. It can be found in a cube by length*width*height. It can be found in a cylinder by doing pi*radius^2*height. For a sphere it can be found by using (4 × π × r^3)/3. It can be found in a cone by doing (π × r^2 × h)/3. In a pyramid you can use (B × h)/3.

d) A student suggested that purple flowers are more likely to be visited by bees than white flowers.
Use your knowledge of natural selection to suggest how this might affect the number of purple and white flowers in the wild.
Answer: the purple flower is very attractive than the white flower
Explanation:
As more bees visits the purple flower there is less competition between the white.flowers. And as more purple flower is used by the bees the population of purple flower decreases and of the white flowers increases..

What is the purpose of a trophic pyramid?
Explanation:
An ecological pyramid (also trophic pyramid, Eltonian pyramid, energy pyramid, or sometimes food pyramid) is a graphical representation designed to show the biomass or bioproductivity at each trophic level in a given ecosystem.
The images above all illustrate the presence of a vestigial structure. What is this structure and why is it no longer used for its original function? A) Sacral vertebrae have disappeared in modern man. They are no longer needed as man stood more and more upright. B) Lumbar vertebrae. As man became bipedal, the vertebrate became shorter and wider. These particular vertebrate disappeared. C) Coccyx or tailbone is the remnant of a lost tail. The tail was used for gripping as well as an aid in balance and mobility. D) Iliac blade. This part of the pelvis was shortened and widened as a requirement for keeping the center of gravity stable while walking.
Answer:
C, the Coccyx
Explanation:
What is the purpose of a gene
Answer:
Genes are a set of instructions that determine what the organism is like, its appearance, how it survives, and how it behaves in its environment. Genes are made of a substance called deoxyribonucleic acid, or DNA. They give instructions for a living being to make molecules called proteins.
Explanation:
Genes tell your body how to make all its proteins. Each new cell in the growing embryo receives a full set of genes. But not every cell needs to make every protein and cells make some proteins only at certain times. Some genes are instructions for proteins that regulate the activity of other genes.

How does reproductive isolation differ in sympatric modes and allopatric modes of speciation?
Answer:
In allopatric speciation the groups are reproductively isolated and diverge due to a geographic barrier. In sympatric speciation, reproductive isolation and divergence occur without geographic barriers, for example polyploidy.

What do you think happens to a fish’s behavior in cold climates during winter explain
Answer:
it changes just as the weather changes
Explanation:
so as it gets colder the fish get colder as well meaning that the fish will expect its habitat to turn warmer just as we humans (some of us aliens jkjk) want warmth when we are cold its the same thing with fishes

4- Las plantas que viven en sitios húmedos y con poco sol tienen raíces poco profundas. Las que viven en sitios de mucho calor tienen raíces muy profundas. ¿Por qué?
Esto es debido a que en los lugares húmedos las plantas absorven el agua con las hojas y no necesitan hacer crecer la raíz para buscar agua. En cambio, las plantas que viven en lugares calurosos necesitan agua por lo que expanden las raíces hacia abajo para poder encontrar líquido e hidratarse.
Geologists studying a local rock formation measure the amount of matter in the rock. This measurement is known as the rock's __________.
mass
density
weight
gravity
Answer:
Mass
Explanation:
Mass is defined as the amount of matter in a substance. It is usually measured by balances such as the beam balance and scales. It is measured in grams or kilograms depending on the size of the body.
The process of Rock formation involves how a rock is formed which is usually by sedimentation or cooling of magma in volcanic eruptions. In rock formation study,the geologist measures the mass of the rock which enables knowledge of the amount of matter in the rock. This is be used to determine the weight of the rock and the rock type and properties.
Answer:
The measurement is known as the rock's mass.
Explanation:
The mass of an object is the quantity of matter that the object contains. It can be determined or measured by the use of; beam balance, top pan balance etc. The value of the mass of an object does not change regardless of its location on the surface of the earth or at other planets. the mass of object is measured in Kilograms.
Rock formation is a process by which a rock is formed. Either by sedimentation or cooling of magma. In studying the rock formation, the geologist measures the mass of the rock. He/ She would be able to know the amount of matter in the rock, which could be used to determine the weight of the rock.

During their early stages of development, the embryos of reptiles, birds, and mammals look very similar. The embryos of reptiles, birds, and mammals also have many of the same structures and develop in similar patterns. This suggests that reptiles, birds, and mammals... *
Answer:
share a common ancestor
Explanation:
The similarity in their embryos and embryonic development suggests that reptiles, birds, and mammals share the same ancestor.
Similarity in the structure and development of embryo is one of the evidences that is been used by scientists to support the theory of evolution of species. According to the theory of organic evolution, all organisms are on earth as a result of descent with modifications from common ancestors.
Reptiles, birds, and mammals are all vertebrates. They share some basic characteristics and are thought to have shared a common ancestor before each group took different adaptive channels leading to their differences as they currently exist.
Two separate species of squirrels have evolved after being separated by the Colorado River's erosion of the Grand Canyon. What type of speciation has occurred here?
A. Allopatric Speciation
B. Sympatic Speciation
C. Disruptive Selection
D. Group Behavior
Answer:
Option A
Explanation:
In this case the two species of squirrels have evolved when their combined population got divided into parts and was separated as a cause of natural calamity i.e Colorado River's erosion of the Grand Canyon, thereby forced to live in two different geographies and hence evolve differently from each other. The two geographies mentioned above remain disconnected by any natural barrier thereby restricting successful mating of the two population groups of squirrels.
hence, option A is correct
Answer:
Allopatric Speciation is Correct for all future users.

you think this is limiting? How could this affect scientists search for life beyond Earth?
Answer:
I think there is life beyond earth. Actually there most definently is. I think in a way it could be limiting. It's the fcat that the ones out there may not even be able to receive the message as fast as we please. Who knows, it could be years, decades, maybe centuries before they make actual contact with us. Then again, maybe they already have. But, the way this could affect the study is the fact that (I doubt it) but maybe a message could be sent the wrong way, or they misinterpret it. That's the only think I can get off. Anyway, this can also depend on how much funding is going into space. This also brings up the question, "How much do we know about our own planet?
