Answer:

The first answer is rainfall, and the second answer is the last one

Explanation:

1.

Rainfall is measured with a rain gauge in inches/millimeters - Most modern rain gauges generally measure the precipitation in millimetres in height collected on each square meter during a certain period, equivalent to litres per square metre. Previously rain was recorded as inches or points, where one point is equal to 0.254 mm or 0.01 of an inch.

2.

Climate is the weather conditions prevailing in an area in general or over a long period. The other 3 describe the weather conditions in a place for just a week, or day while climate is measured annually (basically over a long time)

Good luck with the rest of your exam, I hope you catch up with all your work and do well :)

Answer:

Some physical characteristics, such as the color of the human skin or eyes, are controlled by at least two genes. These traits are known as polygenic traits. The number of genes that determine the color of the iris is unknown, but the most significant of them are found in Chromosome 15 and they are named OCA2 and HERC2. These genes are associated with the production of melanin.

Explanation: Polygenic inheritance describes the inheritance of traits that are determined by more than one gene. These genes, called polygenes, produce specific traits when they are expressed together. Polygenic inheritance differs from Mendelian inheritance patterns, where traits are determined by a single gene. Polygenic traits have many possible phenotypes (physical characteristics) that are determined by interactions among several alleles. Examples of polygenic inheritance in humans include traits such as skin color, eye color, hair color, body shape, height, and weight.

Evaporation occurs when air that is warmer than water comes into contact with the water's surface, hence option A is correct.

As a liquid transforms into a gas, evaporation, a sort of vaporization, occurs on the liquid's surface. For instance, a high concentration of the evaporating substance in the surrounding gas significantly slows down evaporation when humidity affects the rate of evaporation of water.

It takes in moisture from garden soil as well as the biggest lakes and seas, and the level of the water will decrease when it is heated by the sun.

Therefore, solar energy, or heat from the sun, is what causes the evaporation process to occur, hence option A is correct.

Answer:Once you're infected, viruses invade host cells within your body. They then use the components of the host cell to replicate, producing more viruses. After the replication cycle is complete, these new viruses are released from the host cell. This usually damages or destroys the infected cells.

Explanation:

There are five lines of evidence that support evolution: the fossil record, biogeography, comparative anatomy, comparative embryology, and molecular biology.

Answer:

Earthworms need oxygen just like humans, but they don't have lungs like we do. They have a special skin that allows them to “breathe” oxygen right through it. ... This means the amount of oxygen inside the earthworm will always be less (lower concentration) than the area outside of the earthworm (higher concentration).

Answer:

They both had a tail as an embryo.

Explanation:

Both human and dogs have tail as an embryo. Temporary tail-like structures are present in the human embryo. These tail like structure develop around the fifth or sixth week of gestation, having about 10 to 12 vertebrae and removed when it reached to its full development stage while on the other hand, tail present in dog's embryo also developed with time and we can see when the dog baby is fully formed.

Answer:

They both had a tail as an embryo.

Their arm and leg structure is similar but may have a different function.

Explanation:

Vestigial structures are those body parts that have lost or reduced their original function during the evolution of a species. These vestigial structures might be found in many animals, including human beings. Vestigial structures were plenty functional for common ancestors. But with evolution, they degenerated, stunted, and became rudimentary for some of the new species.  

During the first 4 months of embryogenesis, all mammals have a tail at some point in their development. Dogs develop this structure and keep it during their whole lives, but humans lose it with time during embryogenesis. The tail disappears, and its forming vertebras get fussed with each other composing the coccyx, which represents a vestigial structure. This tailbone is the remnant of a missing tail.

In many animals, the function of the tail is to stabilize, equilibrate and mobilize. But in humans, the coccyx, located at the end of the vertebral column, has lost this original function.

The fact that whales, humans, and dogs all have the same bones in the same order, but they matured differently in later embryological development, is an example of homologous characters.  

Homologous characters have the same fundamental structures. They also share the same relations with adjacent structures, and they have the same embryological development.  

These structures might show variations between organisms exhibiting them, according to their function and to the environment in which the organism lives.  

These homologous characters are common in organisms related and that share a common ancestor.

Explanation:

brainliest plz?

The ecosystem which is most likely has the greatest biological diversity and therefore the highest sustainability is a rainforest that has many types of plants and animals. Therefore, the correct option is D.

An ecosystem refers to the biological community where the biotic as well as the abiotic components interact with each other and influence each other.

It encompasses all the living organisms in a specific area as well as physical and chemical factors that shape their environment such as air water soil climate and environment. They play an important role in functioning the earth's biosphere, as they provide a range of essential services.

The study of ecosystem and interaction between is components is referred to as ecology. Hence, the correct option is D.

Answer:

Explanation:

The answer would be 502 grams because of the law of conservation of mass, you can't create or destroy mass so then 2 grams plus 500 grams is 502.

Answer:1,000 grams

502 grams

500 grams

498 grams

Explanation: The answer would be 502 grams because of the law of conservation of mass, you can't create or destroy mass so then 2 grams plus 500 grams is 502. I am 100% positive that B is correct.

Answer:

One of the most noticeable effects of gravity in the solar system is the orbit of the planets. The sun could hold 1.3 million Earths so its mass has a strong gravitational pull. When a planet tries to go past the sun at a high rate of speed, gravity grabs the planet and pulls it towards the sun
