Genotype Ratio: 1:4
Phenotype Ratio: 1:4
Explanation:
Tt x tt
So, it tells us that for sure the mother has 2 recessive alleles and the father has for sure at least 1 dominant allele and 1 recessive allele (we know this because the offspring can only have a recessive trait if the offspring has 2 recessives, this can only happen if the father has a dominant and a recessive allele). If you put this into the Punnett Square you should find that the probability of Tt is 50% and tt is also 50%.
this would make both the Genotype and the Phenotype 1:4

How did Wegener think that continents went together?
Answers
Explanation:
Fossils of similar organisms across widely disparate continents encouraged the revolutionary theory of continental drift. He called this movement continental drift. Pangaea. Wegener was convinced that all of Earth's continents were once part of an enormous, single landmass called Pangaea.
Answer:
Wegener suggested that perhaps the rotation of the Earth caused the continents to shift towards and apart from each other. (It doesn't.) Today, we know that the continents rest on massive slabs of rock called tectonic plates. The plates are always moving and interacting in a process called plate tectonics.

The immune system has two modalities, specific and nonspecific responses. Which of the following is an example of a nonspecific response?
A. an antigen binding to an antibody
B. inflammation at the site of an infection
C. a cytotoxic T cell attacking a pathogenic agent
D. lymphocytes activating plasma cells in the blood
Answers
B. Inflammation at the site of an infection is an example of a nonspecific response of the immune system.
What is non-specific immune response?Non-specific immune responses, also known as innate immunity, are the first line of defense against invading pathogens and are activated immediately upon exposure to a foreign invader. These responses are not specific to a particular pathogen and do not require previous exposure or recognition. Instead, they provide a general response that helps to prevent the spread of the pathogen and contains it until the specific adaptive immune response can be activated.
Examples of non-specific immune responses include physical barriers such as skin and mucous membranes, as well as physiological responses such as inflammation, fever, and the activity of phagocytic cells like macrophages, which engulf and destroy pathogens. Non-specific immune responses also include natural killer cells, which are able to recognize and kill infected cells, and the complement system, a group of proteins that help to enhance the ability of other components of the immune system to destroy pathogens.

Water has a unique property. Like most liquids, it becomes denser as it cools, but at 4°C it reaches maximum density. Solid ice is less dense than liquid water, which is why ice floats. How would this property protect aquatic life in a lake?
A. The lake would not freeze solid.
B. Predators would be kept out of the lake.
C. Dissolved oxygen would remain in the lake.
D. Heat would be conducted away from the lake.
Answers
Answer:
A
Explanation:
It's A
Due to this unique property of water, the lake would not freeze solid.
What is anomalous expansion of water?The anomalous expansion of water is an abnormal property of water in which it expands instead of contracting when the temperature goes from 4 degree Celsius to 0 degree Celsius and it becomes less dense.
Due to this property of water, the aquatic life is protected deep in water in colder region so we can conclude that due to this unique property of water, the lake would not freeze solid.

how enzymes inhibitions studies in the formulation and development of drugs
Answers
Answer:
Enzyme inhibitors may alter the elimination rate of a particular drug or inhibit detoxication pathways
Explanation:
An enzyme inhibitor is a chemical compound capable of binding to an enzyme in order to reduce its activity. An enzyme inhibitor may bind to an active site and thus decreases the rate of reaction (direct inhibition). Enzyme inhibitors may act 1-to Inhibit detoxification enzymes and 2-reduce the elimination rate of enzyme drugs, thereby having dose-dependent toxicity effects. For example, many medicines are based on the inhibition of Cytochromes P450 (CYPs) proteins, which are a superfamily of enzymes required for drug metabolism.

The answer is DEPENDENT VARIABLE
-edgy 2021
Answers
Answer:
B. Dependent variable.
Explanation:
An experiment can be defined as an investigation which typically involves the process of manipulating an independent variable (the cause) in order to be able to determine or measure the dependent variable (the effect).
Hence, an experiment is used by scientists or psychologists to illustrate how a change in variable affects behavior.
This ultimately implies that, an experiment can be used by scientists to show or demonstrate how a condition causes or gives rise to another i.e cause and effect, influence, behavior, etc in a sample.
In an experiment, there are two (2) main types of variables and these are;
I. Independent variable: this is the variable that is being manipulated or alters and as such it is the cause of a behavior. This variable stands alone.
II. Dependent variable: this variable is the direct effect of the actions of the researcher in an experiment.
Basically, the dependent variable is the variable that is being measured and tested by an experimentalist.
Hence, dependent variable is another term for the responding variable because it responds to an action.

What is Microscope?Microscope: a device that magnifies small objects, giving the user a close-up view of minuscule structures at a scale suitable for observation and analysis.
Even though optical microscopes are the focus of this article, an image can also be magnified by a variety of different wave types, such as acoustic, X-ray, or electron beams, and is then captured using direct or digital imaging, or a combination of these techniques.
The magnifying power of a microscope is a dimensionless ratio that expresses how often the thing under examination seems to be magnified.

Which of these decreases as greenhouse gas pollution increases?
A. Rate of ice-sheet melting
B. Ocean salinity
C. Ocean surface temperature
D. Sea levels
Answers
The climate-changing gases present in the atmosphere are greenhouse gases. An increase in greenhouse gas decreases the salinity of the oceans and sea. Thus, option B is correct.
What are greenhouse gases?Greenhouse gases are the major factor contributing to global warming and climate change. They are present in the atmosphere and have increased with a rise in the level of pollution.
The greenhouse gases have an inverse effect on the salinity or the thermohaline circulation. The increased temperature affects the glaciers and results in the melting of the ice caps thereby increasing the water level and surface temperature.
The increased water level and temperature increase the evaporation rate and elimination along with the circulation rate of the water from the poles and equator resulting in decreased salinity.
Therefore, the greenhouse gases decrease salinity.
