What do homologous and analogous
structures have in common?

Answer:

A) sound wave.

Explanation:

A sound wave is an example of a mechanical wave. Sound waves are incapable of traveling through a vacuum

Answer:

transverse Waves transfer energy at right angle while longitudinal waves transfers energy parallel

Answer:

x and y

Explanation:

x and y have the smallest orbital radius so they are likely to be inner planets while w and z have bigger orbital radius so the probability of them being inner planets is low.

Answer:

Increases redox potential decreases microbial growth inside food.

Explanation:

The redox potential is considered as one of the most complex indicators of the physical conditions of microbial cultures. The measurement of redox potential could be very useful for the determination of qualitative and quantitative parts of the microbial contamination. During the bacterial growth, the redox potential of the medium decreases. Redox potential is a measure of the tendency of a biological species which can be acquire or lose electrons through ionization. If the redox potential of the medium is increases, there will be lower growth of microbes in the food and vice versa.

Answer:

D the upper layers

Explanation:

at first, lifeforms were simple. they got more complex for a variety of reasons, including to adapt to the changing earth. simple organisms will be lower down for that reason.

The lower layers should contain fossils of more complex organisms. So, the correct option is (C).

A fossil is defined as the preserved remains, imprint or trace of something that once lived from a previous geological era. Examples of fossils are bones, shells, exoskeletons, fossilized traces of animals or microbes, objects preserved in amber, hair, petrified wood, and DNA residues. The totality of fossils is known as the fossil record.

There are four main types of fossils which are formed in different way  are conducive to preserving different types of organisms. Fossils are mold fossils, cast fossils, trace fossils and true form fossils.

Fossil layers are fossils that formed in sedimentary rock that formed in layers by depositing and pressing sediments on top of each other.

Thus, the lower layers should contain fossils of more complex organisms. So, the correct option is (C).

Answer:

Karyotypes describe the chromosome count of an organism and what these chromosomes look like under a light microscope. Attention is paid to their length, the position of the centromeres, banding pattern, any differences between the sex chromosomes, and any other physical characteristics.

Explanation:

As this karyotype displays, a diploid human cell contains 22 pairs of homologous chromosomes and 2 sex chromosomes. ... The maternal and paternal chromosomes in a homologous pair have the same genes at the same locus, but possibly different alleles.

Answer:

Contact Metamorphism - Heat

The heat is the main cause, cooling magma affects the rock adjacent to an intrusive body.

Dynamic Metamorphism - directed pressure

It takes place due to grinding two large blocks of rock in a fault zone which causes a directed pressure that leads to heat and the formation of these metamorphisms.

Regional - surrounding pressure

A heat and lithostatic pressure come from depth within the earth.

Impact - Meteorite

By collision of meteorite to earth very high amount of kinetic energy is converted instantaneously to heat and differential stress.

Answer:

Transcription of gene A is not affected

Explanation:

A transcriptional repressor is a DNA/RNA-binding protein that acts to suppress gene expression and/or protein synthesis by binding to target sequences. Moreover, a silencer is a DNA region that binds to particular transcriptional repressors in order to suppress gene expression. In this case, the transcriptional repressor is activated by binding to an effector molecule X (e.g., another protein). In consequence, and since the activated repressor-X complex is not more able to bind the silencer of gene A, it is expected that such complex will not be able to affect transcription of the target gene.

Answer:

CO2 + H2O ---SUNLIGHT--------> C6H12O6 + O2

Explanation:

In the process of photosynthesis, carbondioxide reacts with water molecules in the presence of sunlight forming glucose molecules and oxygen gas. The carbondioxide enters the plant body through small openings called stomata, these stomata opens when there is sunlight whereas water enters the plant body through roots from the soil and reaches to the leaves. In leaves both combine produces glucose which can be stored in different parts of the body and some oxygen is used by the plants in the process of respiration and extra is released through stomata.

Answer:

A good reason why a desert fox shows this pattern of behavior is to protect themselves from cold conditions since at nighttime, it gets very cold in the desert!

Explanation:

Nocturnal is a type of animal behaviour shown when the animals are active at night time and inactive at daytime. Desert fox shows this behaviour so that it can avoid the hot daytime of the desert.

Nocturnal lifestyle is the behaviour adopted by animals that are active at night time and are inactive during the daytime. During the daytime, they rest in the cool burrows, holes and underground canals to prevent the loss of water and to protect themselves from the extremely hot environment.

The desert animals like desert foxes have adapted the nocturnal lifestyle to avoid the extreme heat during the daytime and sleep in their underground burrows. Instead, they come out during the night when it is cool in deserts to eat and play.

Nocturnal lifestyle is shown by the diurnal animals that rest and sleeps in the burrows, holes and cool places during the hot time of the day.

Therefore, the desert fox shows a nocturnal lifestyle.

Answer:

First what is it? Carbon cycle is, nature's way of reusing carbon atoms, which travel from the atmosphere into organisms in the Earth and then back into the atmosphere over and over again. Most carbon is stored in rocks and sediments, while the rest is stored in the ocean, atmosphere, and living organisms.

1.Carbon moves from the atmosphere to plants. In the atmosphere, carbon is attached to oxygen in a gas called carbon dioxide (CO2). Through the process of photosynthesis, carbon dioxide is pulled from the air to produce food made from carbon for plant growth.

2.Carbon moves from plants to animals. Through food chains, the carbon that is in plants moves to the animals that eat them. Animals that eat other animals get the carbon from their food too.

3.Carbon moves from plants and animals to soils. When plants and animals die, their bodies, wood and leaves decays bringing the carbon into the ground. Some is buried and will become fossil fuels in millions and millions of years.

4.Carbon moves from living things to the atmosphere. Each time you exhale, you are releasing carbon dioxide gas (CO2) into the atmosphere. Animals and plants need to get rid of carbon dioxide gas through a process called respiration.

5.Carbon moves from fossil fuels to the atmosphere when fuels are burned. When humans burn fossil fuels to power factories, power plants, cars and trucks, most of the carbon quickly enters the atmosphere as carbon dioxide gas. Each year, five and a half billion tons of carbon is released by burning fossil fuels. Of this massive amount, 3.3 billion tons stays in the atmosphere. Most of the remainder becomes dissolved in seawater.

6.Carbon moves from the atmosphere to the oceans. The oceans, and other bodies of water, absorb some carbon from the atmosphere. The carbon is dissolved into the water.

The correct answer is - C. An increase in the sustainability of an ecosystem.

Explanation:

Biodiversity is the variety of different biological species and populations on the earth or in an ecosystem. Biodiversity helps in maintaining health by providing food and other resources. Higher biodiversity healthier the earth.

Sustainability is the ability to maintain the ecological process and its structure and function in case of external stress for a longer time. The more sustainability of an ecosystem the healthier the ecosystem. The biodiversity of an ecosystem provides sustainability to the ecosystem. An increase in biodiversity will lead to a more sustainable ecosystem.
