Answers
Answer: A
Explanation: Hull Fouling
The introduction of Caulerpa, also known as killer algae, into California was ultimately the result of the aquarium trade in exotic, nonnative aquatic species. The correct option is b.
What is exotic species?Exotic species are those that have been introduced, either intentionally or unintentionally, by humans into an ecosystem where they did not evolve. Such introductions are most likely a natural occurrence.
Endemic species are those that are found only in one region and nowhere else on the planet.
Invasive species have the potential to extirpate native plants and animals, reduce biodiversity, compete with native organisms for limited resources, and alter habitats.
This has the potential to have significant economic consequences as well as fundamental disruptions to the coastal and Great Lakes ecosystems.

A. Fragmentation
B. Spore formation
C. Fertilization
D. Gamete formation

Answer and Explanation:
C...
Gamete formation and fertilization takes place during human reproduction. Therefore, option (C) and (D) are correct.
What is sexual reproduction in humans?Human fertilisation produces a human child via human reproduction, which is reproduction. It usually entails activity between a sexually mature male and female person.
Copulation, or sexual intercourse, involves the insertion of the erect into the vagina and the ejection of spermatozoa from the seminal fluid (semen) into the female genital tract. The ovum in the outer portion of the fallopian tube is subsequently fertilised by spermatozoa as they travel from the vagina via the uterus to the tube.

Which of the following would be affected when a protein is denatured?
a.) amino groups
b.) primary structure
c.) side chains
d.) tertiary structure
Answers
"b" why because primary structure needs protein and if protein denatured,primary structure will affected instantly!
#followandheartallmyquestion
When a protein is denatured by chemical, heat or other substances, the primary structure remains intact. Hence, the correct answer would be the tertiary structure.
Denaturation of proteins generally causes the breakage of weak bonds on which the folding and the entire protein structure is built. When this happens:
the peptide bonds between the component amino acids remain intact. Hence, the primary structure is conservedthe destruction of other bonds means that the secondary and tertiary structures are affected.Agents that are capable of denaturing proteins include high temperature, changes in acidity/basicity, UV radiation, high concentration of salts, and so on.
The correct answer as to which would be affected when a protein is denatured in this case would, therefore, be the tertiary structure.

Which is NOT an example of a renewable energy source?
O Coal
O Wind
O Water
O Sun
Please help ASAP
Answers
Answer:
coal
Explanation:
wind and water never end so they're renewable and the sun like ofc also never ends
but you can run out of coal
Answer:
Coal
Explanation:
A renewable energy source is a source of energy that is not likely to run out within our lifetimes. The wind will never go away. Neither will the Sun. Although we know that the Sun is going to explode, since it is a star, it is not likely that it will happen in our lifetimes. Water is also not likely to run out completely within our lifetimes. However, coal on the other hand will run out some day; it takes millions of years to make coal, and people are using it faster than it can replenish itself.
A good way to remember which energy source is renewable and which is not is to look at how much it pollutes. Fossil Fuels such as Coal, Oil, and Natural Gas pollute a lot, and they are all nonrenewable energy sources. On the other hand, clean energy sources such as solar power, hydropower (water power), and wind power do not pollute as much, and they are all renewable resources. (Please note that this relationship is not causation, but rather correlation. The amount of pollution an energy source emits does not cause it's renewability.)

Which component of weather results in stormy, cloudy weather?
A. High pressure
B. Low pressure
C. High temperature
D.Low temperature
Answers
Explanation: Low-pressure areas are places where the atmosphere is relatively thin. Winds blow inward towards these areas. This causes air to rise, producing clouds and condensation. Low-pressure areas tend to be well-organized storms.
Low pressure component of weather results in stormy, cloudy weather. Therefore, option (B) is correct.
What causes cloudy and stormy weather?Low pressure systems in the atmosphere are often to blame for the weather patterns of cloudy and stormy conditions. When there is low pressure in an area, it causes the air pressure to rise, which can result in the development of clouds and the production of precipitation. Low pressure systems have a tendency to produce air that is unstable, which can lead to severe weather such as thunderstorms, hurricanes, and other forms of severe weather.
In contrast, high pressure systems almost always result in weather that is free of clouds and precipitation. This is because the air that surrounds the high pressure area is sinking and remaining relatively still. The formation of gloomy and stormy weather can also be influenced by a variety of other factors, including temperature, humidity, and the direction and speed of the wind.

The correct answer is B. All organisms go through both mitosis and meiosis.
Explanation:
The same mechanisms of chromosomal segregation are at work in both mitosis and meiosis -- centrosomes, microtubules and motor proteins. Both mitosis and meiosis are multistage processes. The stages are interphase, prophase, metaphase, anaphase and telophase. The same general processes occur in each of these stages for mitosis and meiosis.
You have engineered a protein that contains a nuclear localization signal, a nuclear export signal, a C-terminal peroxisomal targeting signal, and an import signal for the endoplasmic reticulum. with all of these signal sequences, where would you expect to find the protein after its synthesis?
Answers
Answer:
The correct answer is - Endoplasmic reticulum
Explanation:
In this case, the N-terminal endoplasmic reticulum signal sequence of the engineered protein is recognized primarily. This signal is used to target the particular protein co-translationally, to the endoplasmic reticulum for post-translational modifications or changes.
Such post-modifications are glycosylation that taken place in the lumen of the endoplasmic reticulum. Other than Glycosylation Protein phosphorylation , Sumoylation and Ubiquitination, are other changes or modifications.

If the bird population is directly proportional to the average monthly temperature, which month would have the LOWEST temperature?
Question 1 options:
8- August
12-December
1- January
10 October
Answers
Answer:
December
Explanation:
If the bird population is directly proportional to the average monthly temperature, 12 december would have the lowest temperature.
What is population?
The population of an organism can't survive if it exceeds it's carrying capacity. If animal population increases the population that eat that animal might also increase
The causes that affect population growth animals that if there are more plants than usual in area, populations of animals that eat that plant may increase. If animal population increases the population that eat that animal might also increase.
The effects of animals population can be dangerous and when population exceed the carrying capacity of their environment, animal suffer of malnutrition and disease. When predators became scarce due to over population, the weekar species of animal start or die in other ways .
Therefore, If the bird population is directly proportional to the average monthly temperature, 12 december would have the lowest temperature.
