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.
Explanation:
Originally the Continental Drift Theory was not well received by other scientists. Why?
A. There was a competing theory at the time which was more believable.
B. There was no data showing the continents ever moved.
C. The scientists didn’t know the force responsible for moving the continents.
D. The scientist presenting the data was unreliable.
Answer:
C
Explanation:
The main reason that Wegener's hypothesis was not accepted was because he suggested no mechanism for moving the continents. He thought the force of Earth's spin was sufficient to cause continents to move, but geologists knew that rocks are too strong for this to be true.

12. Study the image of a chromosome. Which of the following statements about
the chromosome is true?*
chromosome
A. Each half of the chromosome is genetically identical.
B. Once formed, a chromosome always stays in this X shape.
C Each half of the chromosome contains genetically different material
D. The pinched middle of the chromosome is what allows it to split during mitosis.
Answer:
A. Each half of the chromosome is genetically identical.
Answer:
C
Explanation:
I would say it is C.
Each cell has 23 chromosome (46 in total). 23 is from our mother, 23 from our father. So this would mean the chromosomes are not genetically identical, hence we have variation.

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.

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.

Why do cells need to replicate their DNA?
Answer:
Replication is an essential process because, whenever a cell divides, the two new daughter cells must contain the same genetic information, or DNA, as the parent cell. ... Once the DNA in a cell is replicated, the cell can divide into two cells, each of which has an identical copy of the original DNA.
Explanation:
DNA is the genetic material, which is found in every living cell. The DNA is made up of a pentose sugar, nitrogenous base, and phosphate backbone.
DNA is a genetic material that transmits the information from parent cell to daughter cell using DNA replication.
DNA replication is an essential process in which the daughter cells inherit information from the parent cell.
Cell division is a process through which a DNA copies its genetic material and delivers it to the newly forming daughter cells.
The genetic information in the daughter cell must contain the same set of rules and instructions to carry out the vital processes. The information is present in the original copied form of DNA from the parent.
Thus, DNA replication is necessary for the continuity of life and similar genetic information presents the daughter cells.

Due to climate change, places that used to be colder are now warming up, allowing new invasive species to establish themselves. What is one way that warming conditions are beneficial to invasive species?(1 point)
Warm weather allows animals to travel farther and longer because they do not need to hibernate for winter.
Warming leads to longer life spans for the animals because none die due to exposure to the cold.
There is more food and shelter available since the growing season is year round.
If the location used to be too cold for non-native species, it is now warm enough to allow them to exist.
(Q1)An introduced species is not necessarily harmful to the environment; an invasive species has a negative effect.
(Q2) the number of species in a community
(Q3) If the location used to be too cold for non-native species, it is now warm enough to allow them to exist.
(Q4) It reduces biodiversity by reducing successful mating in native species.
(Q5) Large because it has led to several significant changes, including new invasive species and loss of natives.
Explanation:
i just did the quick check
Warming conditions are beneficial to invasive species because if the location used to be too cold for non-native species, it is now warm enough to allow them to exist. Option D is correct.
What are invasive species?When species move and establish in a new area, out of their original distribution range, they might be considered exotic or invasive, according to their
• reproductive rate,
• population growth, and
• interaction with native species.
When a new species stablishes and overgrow in a new area, negatively affecting native ecosystems dinamics, they are considered invasive species.
The introduction of invasive species has ecological, economic, socio-cultural consequences.
In the new areas, these species have less environmental pressure and better conditions than in their origin area -fewer predators, more resources, better nitches-.
These factors favor their establishment because they are adapted to surviving under harder conditions.
They interact with native species by
Competing for resources such -water, place, radiation, exposure, shelter, food, etcetera-.Predating on native species, consuming a wide diversity of prey items, and in many cases, there are no native species that may prey on them.They provoke significant damages in the structure of native ecosystems, causing severe damage in endemic species.
They produce ecological imbalances in the trophic chains and the dynamics of communities. Invasive species are uncontrollable.
Areas that get warmer due to climate change provide a propicious environment for invasive species to stablish and overgrow.
Temperature is not a limmiting factor any more for these species, so they can move and stablish in these areas.
Warming conditions are beneficial to invasive species because if the location used to be too cold for non-native species, it is now warm enough to allow them to exist.
Option D is correct.
