What is rift valley?
A system of intra-continental ridges passes through Kenya from north to south, including the Great Rift Valley.
It is a portion of the Gregory Rift, the eastern branch of the East African Rift, which extends northward into Ethiopia from where it begins in Tanzania to the south. The Arabian, Nubian, and Somalian plates' interactions resulted in the formation of the "Kenyan Dome," a geographical upwelling.
It was once thought to be a component of the "Great Rift Valley," which stretched from Syria to Madagascar. The valley's majority was once part of the Rift Valley Province.
Therefore, The name for the area between the two diverging plates in this picture rift valley.

While scientists have known of DNA's existence for much longer, until 1984 they didn't know that the DNA of each person differed
T/F?
Answer:
The statement is true
Explanation
the statement is wrong because the structure of DNA was discovered in 1953 by James Watson and Francis Crick and they explained it very well. till 1985 everything about the structure of DNA was very well known and the scientist knew that the DNA of each person differs from each other.
Answer:
True!
Explanation:
Ever since many years before 1984, Scientists knew that DNA existed. In 1984, DNA was found to differ for each and every person.

Based on the energy flow between trophic levels in an energy pyramid how much energy would be expected to be found at the secondary consumer level in this pyramid
Answer:
100J of energy is transferred to the secondary consumers
Explanation:
According to the second law of thermodynamics, energy transfer from one trophic level to another is not usually a 100% transfer of energy. This is because the organisms at each trophic level use energy derived from food substances to carry out its activities.
Only about 10% of the energy obtained at each trophic level is transferred to the next trophic level.
This implies that only about 1000J of energy is transferred to the primary consumers and 100J of energy is transferred to the secondary consumers.
Which factor does not alter the rate of hydrolysis of maltose, a disaccharide?
A.temperature of the environment of the reaction
B.pH of the environment of the reaction
C.number of enzyme molecules present
D.size of the substrate molecule
The factor that does not alter the rate hydrolysis of maltose is the number of enzyme molecules present.
Enzymes are biological catalysts that promote various reactions in the body. Enzymes are specific in their action. Therefore, only an enzyme can catalyze a particular reaction. The enzymes work based on a lock and key model.
A disaccharide is composed of two mononosaccharide units. The factor that does not alter the rate hydrolysis of maltose is the number of enzyme molecules present.

Explanation:
which describes the process
Answer:
D. Crossing over which alleles are exchanged
Explanation:
Crossing over or recombination is the process by which segments of a chromosome (alleles) are exchanged between the non-sister chromatids of two homologous chromosomes. The process of crossing over solely occurs during meiotic division.
According to the image attached to this question, a pair of homologous chromosome (one black, one red) are shown. The alleles of two non-sister chromatids i.e. non-identical chromosomes are exchanged in such a way that one part of the first chromosome is present in the second and vice versa. This process is called CROSSING OVER.
Within a cave environment, bat waste products, called guano, are decomposed by organisms such as fungi and bacteria. These are then eaten by
creatures such as flatworms. Larger animals like salamanders eat flatworms. Which correctly represents the energy flow described?
A. Fungi - Bacteria - Salamanders - Guano
B. Bats - Guano - Flatworms - Salamanders
C. Salamanders - Fungi - Bacteria - Flatworms
D. Guano - Bacteria - Flatworms - Salamanders
Answer:
D
Explanation:
The correctly represents the energy flow described in the given case is - D. Guano - Bacteria - Flatworms - Salamanders
Energy flowEnergy flow is the movement of energy that is transferred from one trophic level to another trophic level but does not revert back. It is always unidirectional and it follows II nd law of thermodynamics.
In the given food chain, energy is transferred from waste products called guano by a bat which does not involve a bat directly, thus it starts from guano, and energy moves to bacteria and then flatworms and ultimately to the salamanders.

A.
Offspring can be produced more quickly than by asexual means.
B.
Genetic diversity makes organisms respond differently to environmental changes.
C.
The offspring is genetically different.
D.
A lot of time and energy is required for making gametes and finding mates.
Answer: D. A lot of time and energy is required for making gametes and finding mates.
Explanation:
A disadvantage of sexual reproduction is that a lot of time and energy is required for making gametes and finding mates.
WHAT IS SEXUAL REPRODUCTION:
Sexual reproduction is a kind of reproduction that involves two organisms. Sexually reproducing organisms produce gametes or sex cells. One organism called the male contributes a gamete called SPERM while the female organism produces EGG. Sexual reproduction ensures that genetic diversity occurs in the offsprings produced as they are genetically different. However, a disadvantage is that it takes a lot of time and energy to make gametes and finding mates.Learn more: https://brainly.com/question/9775272?referrer=searchResults

Delta and Alpha are the same distance from the equator, and they are both near the ocean. Using the information in the map, how does the air temperature of Delta compare to the air temperature of Alpha? Why?
The image of this question is missing, so i have attached it.
Answer:
Explained below.
Explanation:
From the image attached, we can deduce that;
- The air temperature of Delta will be warmer than Alpha.
- The reason is because the wind will push ocean water that's turning and following the coasts and thereby making energy to be transferred from the ocean to the air at Delta and also from the air to the ocean at Alpha.
Answer:
I am doing the same test as you, so it is D. warmer than Alpha. The winds push ocean water that turns and follows the coasts. A lot of energy is transferred from the ocean to the air at Delta, and only a little energy is transferred from the ocean to the air at Alpha.

Adapting to Life at Sea: Take a look at this article from Natural History Magazine. Explain the connection between sea snake's diet, the way in which they eliminate nitrogenous waste, and their need for freshwater. Then explain why this makes life (in at least one way) difficult for them in the ocean.
Answer:
They needs fresh water for drinking purpose.
Explanation:
The Sea snakes favorite food is fish and crustaceans. These sea snakes removes nitrogenous waste in the form of ammonia. They can live in salty water but needs fresh water for drinking purpose. This makes life difficult for sea snakes in the ocean because sea snakes needs fresh water to become hydrated and the sea water is salty which they can't drink so they depends on the rainfall for drinking purpose.
The sea snakes excrete their nitrogenous wastes via cloaca and some of it from the skin.
Sea snake
The snake excretes solid as well as liquid wastes from the cloaca but sometimes the flow of excreta gets disturbed due to change in the osmolarity between the environment and the body. The oceanic water is saline which is responsible for changing the osmolarity.This is making their survival difficult in the ocean.
