If Y chromosome of males is involved in fission then, it results in XY chromosome set, it results in a male child.

Answer 2
I’m pretty sure it’s Female, because we were all born female at first, that’s what I heard on a video

1. Do you think it is fair that Watson and Crick were credited with the discovery when so many other scientists were involved? Why or why not? Think about your opinion and then back it up with at least one fact. ​

Answers

Answer:

No.

Explanation:

I don't think it is fair that Watson and Crick were credited with the discovery when so many other scientists were involved because all other scientists also contributed in the work and work harder for it so the credit must be given to all scientists. If the credit will not given to other scientists so it is an unfair act so my opinion is against the credit given to Watson and Crick.

Which statement best describes how a catalyst can speed up a chemical reaction?
The catalyst decreases the activation energy needed.
The catalyst increases the concentration of products.
The catalyst binds to enzymes to release substrates.
The catalyst increases the concentration of reactants.

Answers

Explanation:

The catalyst decreases the activation energy needed.

Catalyst can speed up a chemical reaction by decreasing the activation energy needed. Thus option a is correct.

What is catalyst?

Catalyst is defined as a material that allows a chemical process to happen under new circumstances or at a typically faster rate.

It can also be defined as an additive ingredient that can speed up a reaction without being consumed during the process.

There are basically four types of catalyst.

Homogenous catalystHeterogenous catalystHeterogenized homogenous catalystBiocatalyst

Nickel, When making margarine out of palm oil, Ni is employed. In the Haber process, iron (Fe) is employed etc. are some of the example of catalyst.

Thus, catalyst can speed up a chemical reaction by decreasing the activation energy needed. Thus option a is correct.

Answers

Answer:

True.

Explanation:

Researchers and scientists are not making any progress in treating or curing AIDS because the virus incorporates itself into the host cell's DNA and the medication is unable to reach that place so the virus is safe from the medication and remains in the host cells. This diseases can't be cure but can be prevented of spreading further in the body through medication such as antiretroviral therapy (ART).

Which of the statements are characteristics of a good hypothesis? -is developed from data that cannot be replicated -relies heavily on cutting edge technology -is created from careful research and logical reasoning -is based only on a presentation by an expert in the field -is able to be tested using validated techniques

Answers

Answer:

is created from careful research and logical reasoning

is able to be tested using validated techniques

 

Explanation:

A hypothesis can be defined as a prediction/expectation that is made in order to understand a phenomenon from the real world. This prediction must be testable and measurable by using the scientific method. In science, a good hypothesis clearly defines the relationships between two or more variables (independent variables and dependent variables). Moreover, a good hypothesis must also be written in simple and precise language, which means that its statements must be understandable (and verifiable) for any person and/or researcher working in the field.

What’s 2 similarities and 2 differences between the Earths layers and the atmospheric layers?

Answers

Answer:

Atmosphere layers. Earth's atmosphere is divided into five main layers: the exosphere, the thermosphere, the mesosphere, the stratosphere and the troposphere. The atmosphere thins out in each higher layer until the gases dissipate in space.

Explanation:

The atmosphere has 4 layers: the troposphere that we live in near the surface of the earth; the stratosphere that houses the ozone layer; the mesosphere, a colder and lower density layer with about 0.1% of the atmosphere; and the thermosphere, the top layer, where the air is hot but very thin.

Which of the following landforms is not made by groundwater erosion?

A. stalactites

B. stalagmites

C. mountains

D. sinkholes

Answers

Answer:

mountains?

Explanation:

Answer: Mountains

Explanation: Groundwater erodes rock beneath the ground surface, especially carbonate rock. Groundwater deposits material in caves to create stalactites, stalagmites, and columns. And we know that a sink whole is also known as a cenote, sink, sink-hole, swallet, swallow hole, or doline, is a depression or hole in the ground caused by some form of collapse of the surface layer. Most are caused by karst processes – the chemical dissolution of carbonate rocks or suffosion processes
