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.

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.

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.

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.

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.
In 1898 Friedrich Loeffler and Paul Frosch found evidence that the cause of the highly contagious hoof-and-mouth disease in livestock was a microscopic infectious particle. It was discovered that this particle requires a host cell to reproduce. Which pathogen is most likely responsible for causing hoof-and-mouth disease in livestock?
Answer:
Enteroviruses.
Explanation:
Enteroviruses is the pathogen that is responsible for causing hoof-and-mouth disease in livestock. Infection of this virus causes a vesicular eruption on the hands, feet, and oral mucosa in the livestock animals which greatly damaged the health of animals. These viruses needs a host cell to reproduce because it is a virus which is non-living outside the living cell.
