Answer:
Bipedalism freed the hands so they could be used to cart food, make and use weapons and other advantages of freed hands. Bipedalism is a much more efficient way to walk and run and this fact is quantified. Bipedalism raised the early proto-human above the horizontal so he could see predators approaching. Bipedalism is a much more efficient design to cool down overheating bodies.

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.

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.

Water flows up through vessels because water is sticky due to cohesion and adhesion.
A.Capillary Action
B.Surface Tension
C. Universal Solvent
Answer:
Capillary Action
Explanation:
Water molecules are attracted to the molecules in the wall of the glass container.Water molecules stick together because of polarity; a water molecule has a slightly positive end and a slightly negative end. Opposite charges attract, creating a cohesive force. Water molecules are attracted to each other. Which are basically the definitions of adhesion and cohesion.

How can these artificial reefs protect biodiversity in the ocean ecosystem?
Answer:The reefs create a shelter for organisms and food
Explanation:Therefore it now created a more populated area for more animals or organisms to live.
Answer:
Plato
Explanation:
Many animals depend on corals for food and protection. By restoring the reefs using this method, they may be able to protect other populations of organisms from declining as well.

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.

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.
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.
Describe how changing a biotic or abiotic factor can influence an entire biome. Could changing biotic or abiotic factors be responsible for the decrease in phytoplankton populations introduced at the beginning of this lesson? Explain.
Answer:
it can change weather things will live or die
Ecological succession occurs when changes to either abiotic or biotic factors have an impact on an entire ecosystem. The replacement of one community of creatures, such as a plant or animal, by another is known as ecological succession. A forest fire is one illustration.
What biotic or abiotic factor can influence an entire biome?An ecosystem's overall health is also influenced by biotic factors such as the diversity of consumers and the presence of autotrophs, or self-sustaining organisms like plants.
Abiotic variables have an impact on an organism's capacity for survival and reproduction. Populations are constrained in their expansion by abiotic forces. In an ecosystem, how these elements interact is crucial.
Therefore, it can change weather things will live or die.

Cell, Tissue, organ, organ systemGeologists 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.

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.
