The science club at Tracy's school is researching how temperature affects fish reproduction. They conducted a study to
find out if raising the water temperature would decrease the number of bass eggs that hatched. They gathered bass
eggs from a local lake and put half of them in each of ten small aquariums in the lab. Half of the aquariums were kept at
room temperature, and the other half were placed in a sunny window. One student recorded that nearly 80% of the
room temperature eggs hatched, while only 50% of the eggs kept in the window hatched. Another student found no
difference in the hatch rate. What should their next step be?
A. The science club should ignore the results of the second student.
B. The science club should conduct an experiment with another type of fish egg.
C. The science club should repeat the experiment again and compare the two sets of results.
D. The science club should use the results to conclude that an increase in temperature decreases the hatch rate
of the eggs.
Answers
It would be best if the science club repeat the experiment again and then compare the two sets of result.
An experiment could be explained as a scientific procedure or set of processes carried out in other to establish the veracity of, or make inference about an hypothesis.
Since the results of the experiment obtained by the two students after the first experiment are conflicting, where, the result of one student infers that there is a difference in the hatch rate of fish at room and sunny temperature and the result of the other student says otherwise.
In other to arrive at a final conclusion, repeating the experiment would be a good move in other to use the result obtained to make comparison between the results.

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.
Answers
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.

Answers
Answer:
plant acids
Explanation:
A lichen consists of a photosynthetic microorganism such as, for example, a photosynthetic green alga, which is surrounded by the filaments of a fungus. Moreover, chemical weathering is a gradual process where chemicals react with the minerals in the rock to form new minerals, oxidize or simply dissolve them. Lichens can lead to chemical weathering of rocks via the excretion of organic acids (e.g, oxalic acid) capable of dissolving minerals and chelating metallic cations.

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?
Answers
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.

(A) Water bodies
(C) Atmospheric gases
(B) Microorganisms
(D) Deeper layers of land
Answers
Answer:
(C) Atmospheric gases
Explanation:
Atmospheric gases are responsible for keeping our surroundings warmer because these atmospheric gases capture the solar radiation and prevent it from going to the space. The stoppage of solar radiation makes our environment warm and we are able to live on the surface of earth. Carbondioxide gas, methane and nitrogen dioxide gases are responsible for warming of atmosphere.

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.

Life is the condition that able an organism to grow, reproduce and perform other activities.
Explanation:
Life is the condition that differentiates living things such as animals and plants from non-living things, these conditions are the ability for growth, reproduction and other activities etc that can't be performed by non-living matter. The main difference between life and non-life or non-living matter is that life uses energy for physical growth and development while on the other hand, the non-living matter doesn't.
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.
Answers
(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:

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.

Environmental conditions has a great affect on the survival, growth and development of organisms. If the environmental conditions are suitable for the organism so it will increase in population while on the other hand, if the environmental conditions are against the organisms so the organisms extinct from that region. The emergence, growth, and extinction of a large class such as dinosaurs is an example of a macroevolutionary pattern. Macroevolution is defined as the evolution of groups larger than an individual species.
