Some form of early Homo is estimated to have evolved into Homo erectus around 1.7-2 million years ago, option B is correct.

Homo erectus is believed to have evolved around 1.7-2 million years ago based on fossil evidence and dating methods. Fossil discoveries, such as the famous Nariokotome Boy skeleton found in Kenya, provide crucial insights into the anatomy and characteristics of Homo erectus. These fossils, along with other archaeological and genetic evidence, suggest that Homo erectus was the first hominin species to exhibit significant anatomical and behavioral differences from earlier hominins.

The emergence of Homo erectus marked a significant milestone in human evolution, as this species had a larger brain size, more advanced tool-making abilities, and potentially even the ability to control fire. These developments laid the foundation for the subsequent evolution of Homo sapiens, option B is correct.

Substitution

Explanation:

Given the information in the question substitution seems like the most appropriate answer. Zoe used 1 cup of slat rather than 1 cup of sugar, she substituted sugar for salt.

Insertion is wrong because Zoe did not add another ingredient, there is still only 2 ingredients.

Transition is wrong because, given the information, because the state(liquid or solid) of the ingredients has not changed. Zoe is still use dry ingredients per say.

And beneficial also seems to be wrong because we don't know if using salt instead was beneficial to the recipe or to Zoe.

A  rubber ball dropped from a certain height has constant uniform acceleration due to gravity. Therefore, rubber ball dropped from a certain height is an example of uniform acceleration.

Elastic potential energy causes a ball to bounce as it is transformed into kinetic energy, which then brings the ball back up. However, the ball does not get high as in the start, because some of its energy is transferred to the floor or into sound.

And also, as the ball hits the ground, or a table, it changes shape for a split second, even though we don't see it. This also requires energy.

Therefore, we can observe that the height of each bounce is a little less than the previous one. Some of the kinetic energy of the ball is retained, when it strikes the floor but all the other is transformed. It loses a bit of its kinetic energy every time the ball bounces and after that it ceases to bounce after several strikes.

While playing tug of war, one person pulls the rope to the left with 50N force and another pulls to the right with 65N force.

A rope will have same tension throughout even when forces acting on both ends are different when the rope considered is massless and inextensible. The rope does not exert any force other than tension. As the tension on an ideal rope is uniform, the forces ( although not same) produce uniform tension.

Explanation:

In a recent experiment, anti-bacterial hand sanitizer was compared to hand soap. Students wash their hands using hand sanitizer or soap and warm water for two minutes; then they dry their hands with paper towels. standard comparison is vigorous hand scrubbing for 2 minutes in warm water, without soap or hand sanitizer, then dry with a tissue. Cleanser ads claim to kill bacteria more effectively than any soap. After washing, the hands are wiped and then the swab is applied to the culture plate and incubated. Finally, the bacterial cultures were counted. students using antibacterial cleansers had the lowest number of bacterial cultures. Although the cleanser works better than hand soap or no soap,  students can do to investigate further the company's claims regarding these cleaners is to try the two brands of hand sanitizer or soap and see the results in the laboratory.

Hand washing is an easy and simple way to remove dirt. Washing hands with soap is an effort to prevent the transfer of bacteria from one person to another, either directly or indirectly. Washing your hands will break the chain of disease transmission.

Further investigations that can be carried out by students for more experimental methods with company claims related to these cleaners are to conduct experiments with these two brands. Students can use the pretest design with control group design. Students do a hand swab after washing their hands with hand sanitizer or soap after that see the results in the laboratory. Calculation of the number of bacteria in the Microbiology Laboratory uses the development of the spectrophotometry method to find out which brand of soap produces the lowest colonies.

The Earth's molten iron core

Explanation:

The Earth's magnetic field is mainly due to the convection current flowing in its molten iron core. It is considered to be a great conductor of electricity and is also dubbed as an "invisible river." If people were to study the magnetic field, they have to follow the movement of the molten iron that flows about thousands of miles every hour. The magnetic field is so strong that it can pass through the earth's core, crust and even reach the space (although it becomes weaker at this point).

The Atlantic Ocean has about 9 degrees Celsius more warmer than the water of Pacific Ocean that leads to the warmer climate of Atlantic basins.

Bacterial vaginosis is a common vaginal infection that is caused by an overgrowth of harmful bacteria in the vagina. The following are the four main characteristics of bacterial vaginosis:

1. Discharge: Women with bacterial vaginosis often experience a thin, grayish-white discharge with a fishy odor.
2. Itching and Burning: Some women may experience itching and burning sensations in the vaginal area.
3. Pain during urination: Pain or discomfort during urination is a common symptom of bacterial vaginosis.
4. No symptoms: In some cases, women with bacterial vaginosis may not experience any symptoms at all.

The treatment of bacterial vaginosis typically involves antibiotics, which can be taken orally or applied directly to the vagina in the form of creams, gels, or suppositories.

It is important to complete the full course of antibiotics as prescribed, even if symptoms disappear before the medication is finished.

In addition to antibiotics, probiotics and maintaining good hygiene practices can help prevent bacterial vaginosis from recurring.

It is important to speak with a healthcare provider to determine the best treatment options for an individual's specific case.

A bee sting can trigger a massive release of histamine, which causes a vasodilation and decrease in arterial blood pressure.

Arterial blood pressure is the pressure exerted by the blood against the walls of arteries as it is pumped by the heart. It is typically measured in millimeters of mercury (mmHg) and consists of two values: systolic pressure, which is the pressure in the arteries when the heart contracts, and diastolic pressure, which is the pressure in the arteries when the heart is at rest between beats. Normal blood pressure for adults is typically around 120/80 mmHg.

In general, the mass of the heavier planets is higher. In general, the denser planets have higher densities. A planet's surface gravity increases as a planet's mass increases.

The density of water is 1.0 g/cm3. Saturn is the only planet that would float if there was a large enough tub of water. The other planets would all float away. Mars and Mercury are the only two worlds where you would weigh less than you do on Earth.

You would be heavier than you are on Earth on the other worlds. This is due to the fact that each planet's mass and gravity are measured in relation to Earth, which is why Earth is assigned a value of 1.

The class of immunoglobulins that attach to the outer surface of B cells and act as a receptor for B cell antigen is IgM.

IgM is the first class of immunoglobulins produced during the primary immune response. It consists of five monomers, each consisting of two heavy chains and two light chains, arranged in a "pentameric" structure. The "tail" of the IgM molecule is attached to the surface of the B cell, while the "head" of the molecule contains the antigen binding site.

The antigen binding site of IgM is highly variable, allowing it to recognize a wide range of different antigens. When an antigen binds to an IgM molecule on the surface of a B cell, it triggers a series of events leading to B cell activation and proliferation, ultimately leading to the production of more specific antibodies to the antigen.
