Answer:
Climate or Global Warming
Dunno what you're asking exactly-
A long-term change in the typical weather patterns that have come to characterize local, regional, and global climates on Earth is referred to as climate change.The phrase is synonymous with a wide variety of observed outcomes that are a result of these changes
What is a long-term change in weather patterns?
Storms, heat waves, floods, and droughts are just a few of the disasters that are getting worse as a result of rising temperatures.Warmer temperatures produce an atmosphere that can hold onto, release, and gather more water. This alters weather patterns such that wet areas get wetter and dry ones get drier. The long-term pattern of the weather in a place is called the climate.Hour by hour, day by day, month by month, or even year by year, the weather might change.A region's climate is determined by its weather patterns, which are typically monitored for at least 30 years.The climates in different places of the world vary.When the weather is consistent for several days or weeks at a time, a weather pattern develops.Cold weather, wet and rainy weather, and hot and dry weather are a few typical weather patterns.Heat waves, flooding, and blizzards can occur as a result of persistent weather patterns. Climate Change Causes... Greenhouse Gases.... Reflectivity or Absorption of the Sun's Energy.... Changes in the Earth's Orbit and Rotation.... Variations in Solar Activity.... Changes in the Earth's Reflectivity.... Volcanic Activity. These phenomena cover changes like sea-level rise, ice mass loss in Greenland, Antarctica, the Arctic, and mountain glaciers around the world, changes in flower/plant blossoming, and extreme weather events, in addition to the higher temperature trends indicated by global warming. The average thickness of 30 well-studied glaciers has declined by more than 60 feet since 1980, indicating that glaciers are thinning. Due to climate changes, the ocean level is rising, glaciers are melting, CO2 levels in the atmosphere are rising, the forest and wildlife are disappearing, and water life is also being disrupted.In addition, it is predicted that many species of plants and animals would become extinct if this trend continues.To learn more about weather patterns refer

When the external temperature gets really hot or cold
Energy produced by your muscles when you exercise
Question 2 (1 point)
Why is it so important to maintain a core temperature of 37°C?
Question 2 options:
Your core temperature doesn't stay at 37°C, it will actually change and reflect the temperature outside.
Your body can only make cells at 37°C, and we need cells because that is what our body is made of.
It is just best to keep that temperature so you don't shiver or sweat.
The enzymes in our cells work best at this temperature and these enzymes are needed to carry out all the reactions that happen in our body to keep us alive.
Question 3 (1 point)
What happens to your enzymes when they get too hot?
Question 3 options:
The enzymes denature and the active site alters, so the substrate can't fit in there properly and chemical reactions don't happen as fast.
The enzyme changes shape, but the substrate still fits in and the chemical reaction can still take place.
The enzyme dissolves and the pieces then need to be rebuilt before they can be used again.

Answer:
The septum pellucidum (Latin for "translucent wall") is a thin, triangular, vertical double membrane separating the anterior horns of the left and right lateral ventricles of the brain.
Explanation:
The septum pellucidum separates the lateral ventricles. The lateral ventricles are divided into two halves by the septum pellucidum, a thin, vertical partition of tissue. It is formed of white matter and is situated in the frontal region of the brain.
The corpus callosum, a sizable bundle of nerve fibers that links the two hemispheres of the brain, is considered to have been influenced by the septum pellucidum.
The biggest ventricles in the brain are called the lateral ventricles. They are situated on each side of the brain, and cerebrospinal fluid is contained inside them (CSF). The CSF assists in removing waste from the brain and spinal cord in addition to cushioning the brain and spinal cord.

ribozymes are rna molecules that have enzymatic activity. this conflicts with the belief of early molecular biologists that
Ribozymes conflict with the belief of early molecular biologists that each enzyme is a polypeptide. A ribozyme is composed of RNA.
A ribozyme (ribonucleic acid enzyme) is an RNA molecule capable of speeding up a chemical reaction.
In consequence, ribozymes have catalytic activity.
For example, within the ribosome, the large subunit of ribosomal RNA acts as a ribozyme that links amino acids during the synthesis of polypeptide chains.
On the other hand, enzymes are specific proteins (composed of amino acids) that can speed up chemical reactions.

A.) 50%
B.) 25%
C.) 100%
D.) 0%
Answer:
c
Explanation:
looked at the answer when i finished the test and got it wrong lol
The roan coat color in horses is also an example of codominance. A “red” roan results from the mating of a chestnut parent and a white parent. Therefore, option (C) 100% is correct.
What is co-dominant inheritance?In the genetic phenomenon known as codominance, both alleles of a gene pair found in a heterozygote are allowed to fully express themselves. Because of this, the phenotype of the offspring is a combination of the phenotypes of both the mother and the father. As a result, the trait does not exhibit dominant or recessive characteristics.
The blue roan horse has hair that is both white and gray, whereas the red roan horse's hair is both white and a reddish-brown color. The hairs of the offspring take on the coloration of both of its parents' coats. This is a situation of co-dominance.
Therefore, the resulting heterozygous progeny will have a 100% codominant inheritance pattern.
