What are the four different variations of bacteria?
Bacteria are classified into five groups according to their basic shapes: spherical (cocci), rod (bacilli), spiral (spirilla), comma (vibrios) or corkscrew (spirochaetes). They can exist as single cells, in pairs, chains or clusters. Bacteria are found in every habitat on Earth: soil, rock, oceans and even arctic snow.
In the image, which animal is both a secondary and a tertiary consumer?
jackal
rabbit
wildcat
lion
will make you brainiest please help
Tertiary consumers in a food chain or food web are animals that obtain their nutrients and energy by feeding on other animals within the same food chain or web.
Tertiary consumers are usually at the top of the food chains in their ecosystem. They have the capacity to feed on animals that consume grasses directly (primary consumers) or even on animals that feed on other animals (secondary consumers).
Secondary consumers, on the other hand, are animals that feed on primary consumers. They, at the same time, serve as prey for tertiary consumers in the ecosystem.
Thus, an animal that has the capacity to be both a secondary and a tertiary consumer would have the capacity to feed on other animals as well as be hunted as food by other members of the ecosystem.

Umm...I'm not entirely sure since there isn't an image displayed prior to the question, but I think out of the options given, the animal that it both a secondary and a tertiary consumer would be the lion. Then again, not entirely sure. I'm taking the assignment now, so I can let you guys know to confirm.
Which abiotic factor is necessary for animals to survive in an aquatic
ecosystem?
Answer:
It's Oxygen.
Explanation:
Some abiotic factors, such as oxygen, are important in aquatic ecosystems as well as terrestrial environments. Terrestrial animals obtain oxygen from the air they breathe. Oxygen availability can be an issue for organisms living at very high elevations, however, where there are fewer molecules of oxygen in the air.

Q5. Arrange the sources of fresh water according to decreasing percentage distribution. Q6. Which among the sources of freshwater can be easily tapped for human use? Q7. Make a short reflection on the availability of freshwater to human use. Will there be enough water in the future?
Surface water (rivers and lakes) are the most available source of fresh water. The other sources of fresh water are largely unavailable.
Water on earth could be fresh water or salt water. The difference between the two is that freshwater is not salty. There is a limited quantity of available freshwater on earth.
Fresh water is found in glaciers, surface lakes and rivers and groundwater.The order of decreasing availability of fresh water on earth is ice> Groundwater > lakes and rivers (surface water).
Unfortunately, the source of freshwater that can easily be obtained for human use is surface water (lakes and rivers). There is only about [tex]1\frac{2}{3}[/tex]% available freshwater in rivers and lakes. About 87% of the world's fresh water supply is locked away in glaciers.
Given the limited availability of fresh water sources, the possibility of an water challenges in the world can not be over emphasized. Definitely, there may not be enough water in the future hence water conservation efforts must be taken seriously.

Gregor Mendel crossed true-breeding plants with yellow seeds (YY) and true-breeding plants with green seeds (yy) to determine what this cross would produce. What is the independent variable in Mendel's experiment?
Question 12 options:
How many tall plants resulted from Mendel's cross
How many yellow plants resulted from Mendel's cross
Color of seeds Mendel chose to cross
Height of plants Mendel chose to cross
Answer:
Color of seeds Mendel chose to cross
Explanation:
This variable does not depend on the other variables you are trying to measure, so it is independent.
In Gregor Mendel cross, the variable does not depend on the other variables you are trying to measure, so it is independent.
What is Gregor Mendel cross?Mendelian Crosses: In one of his experiments on inheritance patterns, Mendel crossed plants that were true-breeding for violet flower color with plants true-breeding for white flower color (the P generation).
Mendel first experimented with just one characteristic of a pea plant at a time. He began with flower color and cross-pollinated purple- and white-flowered parent plants. He was surprised by the results. This led to his law of segregation.
A dihybrid cross is a breeding experiment between two organisms which are identical hybrids for two traits. In other words, a dihybrid cross is a cross between two organisms, with both being heterozygous for two different traits.

How are the shapes of red blood cells and the shapes of nerve cells related to their functions? Thank you!
Answer:
How is the shape and size of red blood cells related to their function?
This biconcave shape allows the cells to flow smoothly through the narrowest blood vessels. Gas exchange with tissues occurs in capillaries, tiny blood vessels that are only as wide as one cell. Many RBCs are wider than capillaries, but their shape provides the needed flexibility to squeeze through.

Choose the stage that best matches the description given.
In warm, humid climates, only dry bones would exist at this stage.
Day 1
Day 2
After day 50
Days 3-17
Days 26-43
Days 18-25
In order for an organism to decompose to the point that only dry bones will remain, it is estimated that in warm and humid environments the process will take roughly three weeks, In which case the options of Days 26-43 as well as after day 50 are correct.
Decomposition is what happens to any dead organic material. Decomposition is when the organic material is broken down into smaller compounds, organic or not. This process is affected by a variety of conditions including:
TemperatureHumidityPresence and species of insectsElements to which the material is exposedand so on. Each of these factors can greatly impact how fast something will decompose.
The question at hand gives us the conditions for the fastest decomposition, given that this process is accelerated in warm and humid conditions. When in these conditions, it is estimated that an organism can take a minimum of three weeks to reach the stage in which all that is left is the skeleton (dry bones).
Three weeks consists of 21 days, however, option 6 that states "Days 18-25" is not being included given that during days 18-21, elements other than bones may still be present. For this reason, the correct answer is any day after day 21, that is, days 22-50+. Therefore, options 5 and 3 can both be considered correct as in those days only dry bones will remain.

Recently there has been a decline in the abundance of life on coral reefs. Scientists are unsure why, but one of the explanations for it is that global temperatures are increasing, making water temperatures rise. These small changes are killing off some of the smallest animals on the reef, which then affects the entire food chain. Which of the following would NOT help protect the diversity of the coral reef?
a: creating coral reefs in cooler waters ?
b: limit fishing around reefs
c : ban places of anchors in reef
d: ban cities into discarding sewage into coral reefs
Limit fishing around reefs would not help to protect the diversity of coral reefs.
What are coral reefs?Coral reefs are among the world's most diversified ecosystem and an underwater habitat that is characterized by corals that construct reefs.
Coral polyps, the invertebrates responsible for reef formation, come in a variety of shapes and sizes, including vast reef-building colonies, graceful flowing fans, and even small, solitary species.
Coral polyp colonies are bound together by calcium carbonate to build reefs.
According to UNESCO, if we continue to generate greenhouse gases at current levels, the coral reefs in all 29 reef-containing World Heritage sites would be extinct by the end of this century.
The Paris Agreement's goal of keeping global average temperature far below 2°C above pre-industrial levels is the only way for coral reefs to survive.
Hence the correct option is B.
