Explanation:

Answer:

Metallic structure with black colour body.

Explanation:

The substance has metallic structure and black colour body will have greatest temperature among other substances because metallic structure and black colour of body heat up very quickly. Metals have free electrons which make it the best conductor of electricity and heat while on the other hand, black colour is a good absorbent which absorb heat very quickly so that's why we can say that metallic solids are the substance that have the greatest temperature.

Answer:

copper

Explanation:

it copper because it have less specific heat (j/kgoc)

The burning of coal to generate has been good in some ways and bad in others. The electricity has allowed for an improvement in many areas of life but the burning of coal is also responsible for a great deal of pollution.

Pollution problem is solved through the use of new technology such as carbon capture and storage, high-efficiency, low-emissions coal-fired power plants, and renewable energy sources such as solar, wind, and hydroelectric power.Carbon capture and storage is a process that captures carbon dioxide emissions from sources such as coal-fired power plants, transports them to a storage site, and stores them permanently underground.

Carbon capture and storage technology is an important tool in reducing greenhouse gas emissions and mitigating climate change.High-efficiency, low-emissions coal-fired power plants are designed to produce electricity with less coal and fewer emissions than traditional coal-fired power plants. These power plants use advanced technologies to improve the efficiency of the combustion process and reduce the amount of greenhouse gas emissions produced.

Renewable energy sources such as solar, wind, and hydroelectric power produce electricity without burning fossil fuels, so they do not produce greenhouse gas emissions or contribute to climate change. These sources of energy are becoming increasingly popular as the technology advances and the cost of producing electricity from renewable sources continues to decrease.

Answer:

The water balance is the relation or balance between the amount of water entering the organism by intake liquids and food and the total output or loss of water lost from the body by different ways such as the kidneys, lungs, bowels, and skin.

Other than water there is the constant input of electrolytes also occurs into the system. Osmotic pressure and the process of osmosis help in ensuring that optimal concentrations of electrolytes and non-electrolytes are maintained in the cells. The excess water or electrolytes, move out of the cells by the osmosis through the semi-permeable membrane that is the cell membrane here.

Answer:

Due to presence of water in these rocks.

Explanation:

The fossils of ferns, rushes, and primitive conifers can not be found in these rocks because these rocks are present under the sea millions of year ago. In this onondaga contains an abundant amount of coral fossils, crinoids, brachiopods, and trilobites due to their aquatic habitat. These organisms are present millions of years ago when this area comes under the sea so that's why the fossils of these organisms are present in these rocks.

Answer:13 is 4  

Explanation:

The heavier ball caused more flour to spread out because it possessed greater kinetic energy due to its greater mass.

Kinetic energy is proportional to an object's mass and velocity, and since both balls were dropped from the same height, they had the same initial potential energy.

However, the heavier ball had more kinetic energy as it hit the flour, causing it to displace more flour than the lighter ball. This can be observed in everyday situations, such as a heavier object causing more damage than a lighter object when dropped from the same height.

Therefore, the relationship between mass and kinetic energy can explain why the heavier ball caused more flour to spread out.

The two pieces of evidence that support the theory of the expanding universe are the red shift of light from distant stars and the existence of cosmic background radiation.

The correct answer is option B.

1. Red shift of light from distant stars: The observation of redshift in the light coming from distant galaxies provides evidence for the expansion of the universe. Redshift occurs when the light waves from an object moving away from an observer are stretched, causing a shift towards longer wavelengths. This phenomenon is consistent with the Doppler effect, where the wavelength of light appears to stretch as the source moves away. The redshift of light from distant stars indicates that galaxies are moving away from us and from each other, supporting the idea that the universe is expanding.

2. Existence of cosmic background radiation: The discovery of cosmic background radiation further supports the theory of the expanding universe. Cosmic background radiation is a faint, uniform microwave radiation that permeates the entire universe. It is believed to be residual radiation from the Big Bang, the initial event that is thought to have initiated the expansion of the universe. The presence of cosmic background radiation provides strong evidence for the hot, dense early stages of the universe and its subsequent expansion.

Based on the information provided in the diagram, it is not possible to determine the identity or nature of the celestial objects labeled X. The diagram only represents the expansion of the universe over time and does not provide specific details about individual celestial objects.

Given the limited amount of data provided, the only sound conclusion to be made is that there has been a change in the ecological/environmental conditions for the ecosystem of the phytoplankton.

The question states that "Researchers determine the population of phytoplankton in an area of the ocean is significantly decreased compared to the previous year", from which we can conclude that there has been a shift in conditions for this ecosystem. Some possible causes include:

and many others.

The observation given is very limited as to the data that it offers. Without additional information regarding other changes to the ecosystem, we cannot predict with any level of certainty what may have caused the decrease in the population of phytoplankton in the area.

The only conclusion that can be made is that there has been a shift of some kind, given that the population of previously thriving organisms does not decrease without reason.

"The derived shared characteristic 'Terrestrial during all stages' should be placed at the base of the tree diagram."

SupThe characteristic "Terrestrial during all stages" is a shared characteristic among all five species being compared in the branching tree diagram. This means that it is a characteristic that all of these species have in common, and therefore it is likely that it was present in their common ancestor.

Since the base of the tree represents the common ancestor of the species being compared, it makes sense to place this characteristic at the base of the tree. This also helps to show that this characteristic is a defining trait of the group of species being compared and that it has been present in their lineage since their common ancestor.

Differences in the physical traits of organisms is a(n) Variation.

In biology, variation is the difference in cells, individual organisms or characters or physical traits among individuals of any species caused by either genetic makeup or an effect of environmental factors. Physical traits are those distinguishable characteristics found in organisms.

Genetic variations can emerge from variant genes known as mutations or processes where genes are rearranged as cells are getting ready to divide which is called genetic recombination. When gene activities are altered by variation, they can introduce different physical traits in organisms.

Oral contraceptives will decrease a woman's risk of developing ovarian and endometrial cancer. The earlier, higher dose oral contraceptive pills have been linked to a slight increase in breast cancer, but not the most recent lower dose pills. Women who use oral contraceptive pills have a slightly higher risk of developing cervical intraepithelial neoplasia, but their risk of developing PID, endometriosis, benign breast changes and ectopic pregnancy are reduced. Both hypertension and thromboembolic disorders can be a potential side effect from using oral contraceptive pills. Condoms and intrauterine devices will not lower her risk of ovarian cancer.
