Earth's temperature has risen by 0.14° F (0.08° C) per decade since 1880, and the rate of warming over the past 40 years is more than twice that: 0.32° F (0.18° C) per decade since 1981. ... From 1900 to 1980 a new temperature record was set on average every 13.5 years; from 1981–2019, a new record was set every 3 years.
A piano player uses her hands for brief quick movements. Which muscle fiber type would you therefore predict to be predominant in these muscles
For brief quick movements, which muscle fiber type would you therefore predict to be predominant in these muscles...Fast twitch muscle fiber type.
There are three types of muscle tissue. 1. Cardiac 2. Smooth 3. skeletal muscles. The skeletal muscle are involved in voluntary movements of the body.
Since the player uses her hand in a voluntary way of movement, therefore she makes use of her skeletal muscles.
With regards to the skeletal muscles, there are two types with regards to speed, we have the slow twitch and the fast-twitch.
The fast-twitch muscle fiber aids in fast movement of the body but for shorter periods compared to the slow twitch.

when nonsister chromatids exchange genes it is called:
Answer:Chromosomal crossover, or crossing over
Explanation:
Chromosomal crossover, or crossing over, is the exchange of genetic material during sexual reproduction between two homologous chromosomes' non-sister chromatids that results in recombinant chromosomes.
Meiosis is the process that produces haploid gametes from diploid cells in the gonads. As a diploid cell progresses through the stages of meiosis I and meiosis II, at what point do the cells first become haploid
Answer:
A
Explanation:
Meiosis occurs in two phases. Meiosis I is the reductive phase, while meiosis II is non-reductive. The point at which the cells first become haploid is at the end of meiosis I, after homologous chromosomes separate.
-----------------------------------------------------
Through Meiosis, a diploid cell (2n) produces four haploid daughter cells (n).
After DNA replication there are two meiotic phases.
The first one is a reductive phase, in which homologous chromosomes separate. In the second phase, the cell suffers a new, not reductive division.1. In the first phase, Meiosis I:
Prophase I: Chromosomes condensate and become visible. Occurs crossing-over between homologous chromosomes. Crossin-over makes the daughter cells to be genetically different from the original one. Metaphase I: Homologous chromosomes randomly align in the equatorial plane. Anaphase I: In this phase occurs the division and independent separation of homologous pairs. Each chromosome migrates to different poles. This separation generates different chromosomal combinations in the daughter cells.Telophase I: Chromosomes of homologous pairs are already in the corresponding poles, and the nuclear membrane forms again in each pole.
Cytokinesis occurs
2. In the second phase, Meiosis II:
Prophase II: Chromosomes condensate again and become visible. Metaphase II: Chromosomes join the spindle apparatus and migrate to the equatorial plane, where they randomly line up. Sister chromatids are holden together until they reach the Anaphase. Anaphase II: Centromeres divide, chromatids get separated, and each of them goes forward an opposite cellular pole. Telophase II: Once in the poles, the chromosomes become lax again, and the nuclear membrane forms again.Cytokinesis occurs.
To answer this question, focus your attention on Meiosis I. During the anaphase homologous chromosomes separate. After this point, the nuclear membrane forms in the telophase, followed by cytokinesis. The result is two haploid cells.

If you throw a ball straight up into the air, when is the kinetic energy the greatest?
Question 4 options:
Right before you catch it after it falls back down.
When the ball reaches the highest point and stops briefly.
Half the distance on the path traveling back down.
Half the distance on the path traveling up in the air.
Half distence on the path traveling up in the air.
Explanation:
When the ball is on thr ground there and not moving there is no potential energy or kinetic energy, when the ball is tossed into the air it will reach maximum height which is determined by how much kinetic energy it has (air resistence is important however) when the ball reaches its velocitu is 0 and all of the energy in the system is potential energy, as the ball falls to the ground that potential energy is converted to kinetic energy
If a ball is thrown straight up into the air, the kinetic energy is greatest when the distance is half on the path travelling up in the air. Thus, the correct option is D.
What is Kinetic energy?Kinetic energy is the energy associated with the body which is under motion. Kinetic energy is directly proportional to the distance, mass and velocity of the object.
When the ball is thrown on the ground and is not moving then there will be no potential energy or kinetic energy as the height and velocity is zero when the object is on ground. When the ball is tossed into the air, it will reach maximum height which is determined by the kinetic energy it has and the air resistance when the ball reaches zero velocity and the greatest kinetic energy is observed when the body attains half of the total distance on the path.
Therefore, the correct option is D.

Stickleback fish protect themselves from predators with a thick covering of brownish plates. They feed on
small aquatic organisms and are preyed upon by bigger fish like trout. In a certain lake, the number of
stickleback fish was documented over a period of 30 years. During this time, the clarity of the lake water
also changed.
1. How did the occurrences of the different traits change over the 30-year period? Use evidence from
the graph to support your answer. Using what you know about natural selection and adaptation, what
generalization can you make based on these changes?
Explanation:
scam fakeeee
just kidding the answer is
every time the differences will change because of the large fishes which kill the small ones and the fishes het big like in one big fish there will be 100 of small fishes like the megladon
during this blood also leaks and the colour of the lake changes
Answer:
In each instance, the variations in fish populations are subject to change due to the predation of larger fish on smaller ones. As a result, the surviving fish grow larger, akin to the manner in which the Megalodon can have hundreds of smaller fish within its body. This process can also result in the release of blood, which has the potential to alter the color of the surrounding water body.

Describe why enzymes are important in all living organisms?
Answer:
Enzymes are important because they make the chemical reactions in cells happen quickly.
Enzymes, by speeding up biological reactions, ensure that all necessary activities in a cell can take place simultaneously and prevent one particular activity from overtaking the entire cell or organism. This is possible because enzymes allow chemicals to react more specifically with only certain substances rather than reacting indiscriminately with any number of different substances within cells.
The most famous example of this enzyme effect is when stomach acid reacts with pepsin that turns food into a liquid. The body then uses this liquid for absorption through the intestines where nutrients are then used throughout the body. It's important for people to have enough enzymes in order to digest their food fully however if

The items that are true about minerals are:
Minerals are naturally occurring substances.Minerals are inorganic and homogeneous substances, which can be found on the surface of the Earth, formed in it naturally / spontaneously.
Minerals are made of one element or one compound of elements.Minerals are found in various forms in nature since they can be of a single element, such as gold, silver, copper, or a combination of elements, such is the case of some chemical compounds such as quartz, which is formed by silicon and oxygen.
Minerals are the components that make up rocks.A rock is a material that can be made up of a mineral or a combination of them, but its chemical composition is variable.
Therefore, we can conclude that a mineral is a substance produced by processes of inorganic nature which are made of one element or one compound of elements.
