Why didn't snow think that miasma theory could explain the initial cases of john harnold and mr blenkinsopp in the 1848 cholera outbreak?
The main reason why Snow thinks that the miasma theory could explain the initial cases of John Harold and Mr. Blenkinsop in the 1848 cholera outbreak is that the air was bad during the time.
This is a result of the belief that diseases are produced due to unhealthy or polluted vapors from the earth or as a by-product of decomposed material.

What do the x’s represent on the mitochondria
The X in the diagram mentions the electron transportation. This process happens during cellular respiration.
The third and last phase in aerobic cell respiration is electron transportation and oxidative phosphorylation. In eukaryotic cells, the mitochondrial membrane contains a collection of protein molecules and electron transport system molecules that make up the electron transport chain. The "highly energetic" electrons produced by the cycle of citric acid are transferred to oxygen through a sequence of processes. As h+ ions are pushed out of matrix of the mitochondria and into the cell membranes space, an electrical and chemical gradient is created from across mitochondrial inner membrane. In the end, oxidative phosphorylation—the method by which cell enzymes oxidize nutrients—produces ATP. The energy generated by the electron transport chain is used by the protein ATP synthase to phosphorylate (add a phosphate group to a molecule) ADP into ATP. The majority of ATP is produced during the oxidative phosphorylation and electron transport chain phases of cellular respiration.

Describe the following spheres of the Earth.
1. Geosphere
2. Biosphere
3. Atmosphere
4. Hydrosphere
Explanation:
1. Geosphere
Geo means “earth.” The Earth’s geosphere (sometimes called the lithosphere) is the portion of the earth that includes rocks and minerals. It starts at the ground and extends all the way down to Earth’s core.
We rely on the geosphere to provide natural resources and a place to grow food. Volcanos, mountain ranges, and deserts are all part of the geosphere.
2. Biosphere
Bio means “life.” The biosphere is made up of all the living things on Earth and it includes fish, birds, plants, and even people.
The living portion of the Earth interacts with all the other spheres. Living things need water (hydrosphere), chemicals from the atmosphere, and nutrients gained by eating things in the biosphere.
3. Atmosphere
Atmos means “air.” The atmosphere includes all the gases surrounding the Earth. We often call the atmosphere “air.” All planets have an atmosphere, but Earth is the only planet with the correct combination of gases to support life.
The atmosphere consists of five layers and is responsible for Earth’s weather. Even though it seems like air is made of nothing, it consists of particles too small to be seen. All these particles have weight that push down on Earth. The weight of air above us is called air pressure.
4. Hydrosphere
Hydro means “water.“ The hydrosphere includes the oceans, rivers, lakes, groundwater, and water frozen in glaciers. 97% of water on Earth is found in the oceans. Water is one of the most important substances needed for life and makes up about 90% of living things. Without water, life would not be possible.
Which of the following correctly gives the electric field at a distance R above an infinitely long line of charge with constant linear charge density λ?
Answer:
Correct option is B) Consider a Gaussian surface (cylinder in this case) of radius r and length l. Then according to the Gauss's Law of electrostatics:∫E.dA=ϵ0qenclosedFrom the symmetry of the surface, we can easily say that the electric field would only be along the radial direction. And the amount of charge enclosed by this cylinder is qenclosed=λ×l and the surface area of the cylinder A=2πrl. So, E×2πrl=ϵ0λl E=(2πϵ01)rλ

Explain the anatomical concepts associated with human development
The anatomical concepts associated with human development deals with the ways and different processes in which the body developed from a zygote which is formed from the fusion of the male and female gamete.
What is Development?This is defined as the prices in which the body grows into maturity from the pregnancy stage to adulthood and it starts with the fertilization process which results in the implantation of the zygote in the uterus.
After some weeks, the parts of the body are formed and are usually visible when a scan is done and the body are formed with adequate supply of nutrients in the body which enhances the process of cell division such as mitosis which is responsible for the growth and repair of worn out tissues.

Attached earlobes are a recessive trait in humans. In the tree below, people
with attached earlobes are shaded in. Which best describes the person
labeled X in the tree
A male with one recessive allele is the correct answer.
What do you mean by recessive allele:
Earlobes of this kind are tiny and fastened firmly to the side of the head. The lack of the dominant allele in the chromosomes is what causes this type of lobe to form structurally. An connected earlobe is expressed by the recessive allele.
The children from this generation are the result of a cross between homozygous recessive (one parent) and heterozygous (two parents) parents. All of the filial 1 (one) generation's kids will therefore carry a recessive allele. The attached earlobe trait won't be present in people with the same dominant allele, though.
Having an attached earlobe a dominating human characteristic?Some people's ear lobes are free, whereas others have them linked to the side of the head. This is caused by a gene that is recessive in people with attached earlobes and dominant in people with detached earlobes. Therefore, in humans, attached ear lobes are recessive.

If 27,500 Kj is at the producer level how many Kj are available for the secondary
consumers ?
By being consumed by another organism, organic molecules from one organism's body can transfer energy from one trophic level to the next. But typically, there is not a particularly effective way to move energy between trophic levels.
The energy stored as biomass at one trophic level, such as primary producers, only accounts for 10% of the energy stored in the following trophic level (e.g., primary consumers).
In other terms, as trophic levels rise, net production falls by a factor of 10.
First-level trophic level members are producers. In the second trophic level, there are primary consumers. The third trophic level has secondary consumers. Because they are at a low trophic level than Tertiary Consumers, Secondary Consumers receive more energy.Since 27,500 Kj energy is present at the producer level, 10% of it will be available at the primary consumer level. This accounts for 2750 Kj of energy.Now, 10% of 2750 Kj of energy will be available at the secondary consumer level. This is equivalent to 275 Kj of energy.Learn more about trophic levels here:
