A kid on a trampoline has 1,000 J of potential energy when they are at the top of a jump. How much kinetic energy will the kid have when they come halfway down?

A. 100 J

B. 250 J

C. 500 J

D. 1000 J

Answers

Answer 1

Answer:

C. 500 J

Explanation:

Given;

potential energy of the kids at the top of the trampoline, P.E = 1,000 J

⇒At the top of the trampoline, the kids have only potential energy.

⇒On half way down, the kids have both kinetic energy and potential energy.

⇒At the bottom of the trampoline, the kids have only kinetic energy.

Based on the statements above, the kinetic energy of the kids half way down is calculate as;

P.E +  K.E = 1000 J

Base on law of conservation of energy,  P.E = K.E

2 K.E = 1000 J

K.E = ¹/₂ x 1000 J

K.E = 500 J.

How is dna like a ladder

Answers

All of the parts of the DNA combine to make rungs. Those rungs are attached together with other rings and the DNA is twisted in a dibble helix to get its shape.

Explanation:

The structure of DNA can be compared to a ladder. It has an alternating chemical phosphate and sugar backbone, making the 'sides' of the ladder. ... These bases make up the 'rungs' of the ladder, and are attached to the backbone where the deoxyribose (sugar) molecules are located.

Some bacteria of the same species and genotype can reduce sulfur anaerobically for energy, depending on the environment. This

an example of...

A)growth and response

B)genotype mutation

C)phenotypic plasticity

D)inclusive fitness

Answers

Answer:

C) phenotypic plasticity

Explanation:

The ability of an organism to change phenotypically according to environmental conditions is known as Phenotypic plasticity.

Organisms might adjust their morphology and physiology to a better performance in environmental heterogeneity.

Generalists species might present a higher magnitude of phenotypic plasticity than specialist species.

Sulfur-reduction bacteria are obligated anaerobic microorganisms, that are metabolically versatile. They might grow either as heterotrophs using organic molecules or as autotrophs using hydrogen and carbon dioxide.    

These bacteria are notoriously adaptable and might be found in many different environments (terrestrial and/or aquatics) where there is no oxygen due to aerobic decomposition of the organic matter.  

They can be found in anoxic sulfuric environments. In the soil, in estuaries mud, in freshwater, in sewage systems, salty waters, thermal water, sulfur deposits, in oil and gas wells, and even in animals and insects intestine.

If Individual 3 has children with a woman that is heterozygous for the genetic disorder, what is the probability they will have an affected child?

Answers

Well let’s draw a punnet square. So first make your four boxes. Now, heterozygous means having two different alleles of a particular gene. We’re going to use the letter ‘A’, but you can use any letter. In your first box there will be the dominant alleles. This can be identified as ‘AA’. A dominant allele is capitalized (A). A recessive allele is lower case (a). So in the first box it will be AA. Move over to the box on the right it will be Aa. Move down one box (on the right side) that will be aa. Now still on the bottom box, move over one to the left. That will be Aa. Since hetero means different, the heterozygous alleles would be Aa which means you have 2/4 probability of the child being affected. So 1/2.

If Individual 3 has children with a woman who is heterozygous for the genetic disorder, then the chance of producing genetically disordered offspring is 25% if the male is heterozygous and 0% if the male is not.

What is the genetic disorder?

A recessive genetic disorder, such as cystic fibrosis, and an autosomal dominant disorder, such as Huntington's disease, are examples of genetic disorders caused by a gene that can express itself in either a dominant or recessive manner. For example, the disease is represented by the aa. If the male is heterozygous for diseases such as "Aa," then he will produce 25% "aa" type offspring when he crosses with the heterozygous female. When a man is purebred AA and crosses with a heterozygous female, then no offspring will be genetically infected.

Hence, if Individual 3 has children with a woman who is heterozygous for the genetic disorder, then the chance of producing genetically disordered offspring is 25% if the male is heterozygous and 0% if the male is not.

hope this helps (:

The mutation shown here is point mutation.

What is mutation?"A changes/alteration in nitrogenous bases sequence of DNA that can results in changes in the genotype and phenotype of an organism is known as mutation."It occurs due to: deletion, insertion, translocation and inversion.During insertion, an extra nitrogenous bases are added to the DNA sequence.During deletion, a nitrogenous bases are removed from the DNA sequence.During inversion, the sequence of nitrogenous bases gets inverted in a DNA strand.In translocation, a sequence of one DNA strand breaks off and attaches to another DNA strand.What is point mutation?"A point mutation occurs in a genome when a single base pair is added, deleted or changed."

Here, the sequence of original strand is A T A C A C and the sequence of mutant one's is T T A C A C. The base A is changed into base T.

Hence, the correct option is: D. Point mutation.

5 facts about the L.A. flood of 1938
I will give you all my points!

Answers

Answer:

1. The Los Angeles flood of 1938 was one of the largest floods in the history of Los Angeles, Orange, and Riverside Counties in southern California.

2. The flood was caused by two Pacific storms that swept across the Los Angeles Basin in February-March 1938 and generated almost one year's worth of precipitation in just a few days.

3. The Los Angeles, San Gabriel, and Santa Ana Rivers burst their banks, inundating much of the coastal plain, the San Fernando and San Gabriel Valleys, and the Inland Empire.

4. Flood control structures spared parts of Los Angeles County from destruction, while Orange and Riverside Counties experienced more damage.

5. It caused $78 million of damage ($1.42 billion in 2019 dollars),[2] making it one of the costliest natural disasters in Los Angeles' history.[3] In response to the floods, the U.S. Army Corps of Engineers and other agencies began to channelize local streams in concrete, and built many new flood control dams and debris basins
