Explanation:
The study of genes that combines with an organism's environment to determine development and behavior is called as Genetics.
The passing on characteristics from parents to their offspring, through sexual reproduction is termed as Heredity.
Inheritance is the practice of transferring assets, securities, debts, rights and obligations after the death of an individual.
In biology the study of heredity is known as genetics. The method of genetic transmission and identification of DNA is the current pillar of biology.
Final answer:
The study of genetics, heredity, and inheritance faces challenges like understanding disease resistance variability, the hereditary nature of genetic and psychological disorders, and the ethical implications of genetic privacy and discrimination.
Explanation:
The challenges surrounding genetics, heredity, and inheritance are numerous, and they play crucial roles in understanding why outcomes from the same disease vary among individuals. Underlying genetic differences can result in one individual surviving a disease while another succumbs—this points to the influence that genetic makeup has on disease resistance and the immune response. Genetic diseases can be passed through family lines following various patterns of inheritance, such as autosomal dominance and recessiveness, X-linked patterns, incomplete dominance, codominance, and lethality.
Furthermore, the genetic components to psychological disorders like depression or schizophrenia are an area of active research. While there is evidence to suggest a hereditary component in these conditions, environmental factors and gene-environment interactions are also significant contributors. Conditions such as childhood obesity can also have a genetic basis, compounded by lifestyle and psychological factors.
An ethical challenge in genetics is the right to privacy concerning an individual's genetic information. Medical, ethical, and social issues, such as discrimination based on genetic information or the ethical implications of genetic editing technologies, are at the forefront of modern genetics discussions.

A prediction is a forecast based on current knowledge or evidence, and among the choices, 'Your best guess as to what will happen next in a text' is the best description. It's related to a hypothesis but more specific, often taking the form of an if-then statement in scientific contexts. The correct answer to the student's question is option (A).
The best description of a prediction from the options provided is A. Your best guess as to what will happen next in a text. A prediction is essentially a forecast based on current knowledge or evidence. It can take the form of an if-then statement, which is often used in scientific contexts, such as If the student turns on the air conditioning, then the classroom will no longer be too warm. This is because a scientific prediction generally follows the logical structure of an hypothesis testing: if the condition A is true, then result B is expected to follow. However, in the context of reading comprehension, it is more about anticipating future events or information in a text, often without a strict if-then structure.
While hypotheses and predictions are related, a hypothesis is more of an informed speculation that forms the basis of an investigation, whereas a prediction is a more specific guess that can result from a hypothesis and is typically used to suggest what the findings of the investigation will be.

Question 3 :
What is the term that correctly identifies this part of a dermal (skin) cell?
Answer and Explanation:
What is the term that correctly identifies this part of a dermal (skin) cell?
cytoplasm. The interior of a cell consists of a jelly-like substance called cytoplasm. It is here that most of the chemical reactions essential for life takes place. Within the cytoplasm are scattered several organelles.
The correct term is D. cytoplasm because it includes all the cellular material within the cell membrane, apart from the nucleus, which applies to dermal skin cells.
To determine which term correctly identifies a part of a dermal skin cell, let's consider each option:
Chromatin: This term refers to the material that makes up chromosomes, which contain the genetic code within the cell's nucleus. Since the nucleus is a part of many cells, this option is not specific to dermal cells.Cytoskeleton: This refers to the network of protein filaments that provides the cell with structure and support. While important, it is not unique to dermal skin cells.Center Vacuole: This is typically a large vacuole found in plant cells that stores water, nutrients, and waste products. Dermal skin cells in humans do not have a central vacuole, making this option incorrect.Cytoplasm: This term describes the gel-like substance inside the cell membrane that holds all cellular organelles except the nucleus. It is found in all types of cells, including dermal skin cells.Therefore, the correct answer is D. Cytoplasm because it encompasses all the cellular material excluding the nucleus within the dermal skin cell, providing a matrix where all cellular processes occur.
Complete question:
Which term correctly identifies this part of dermal skin cell
A. Chromatin
B. Cytoskeleton

Where do animal cells get the molecules, such as proteins, that they use for growth, repair and other life processes?
Animals get protein from diet.
Explanation:Proteins are one of the important part of diet which constitute about one fifth of an ideal diet. This proteins are formed of amino acids. There are 20 amino acids in nature, of which 9 are essential amino acids and 11 are non essential amino acids. The non essential amino acids are prepared in our body by enzymes. But the essential amino acids are needed to be supplied from outside via diet to get access to. So proteins are needed to be present in diet.
Answer:
The cells make them from materials the animal takes in from the environment.

Which is an example of a scientific hypothesis?
Answer:
When you have "if" and "then" in the assumptions
Explanation:
example: "If I give a plant an unlimited amount of sunlight, then the plant will grow to its largest possible size."
A good scientific hypothesis gives a relationship between the variables. An example will be "a certain type of mango has a gene for orange pigment, that mango will be orange coloured". This is then proved by experiments.
What is a scientific hypothesis?A defined idea whose validity or applicability can be tested using defined scientific experiments is called a scientific hypothesis. The scientific hypothesis has always undergone several processes of test and evaluation. It is always presented in such a way that it can be proven to be wrong. That means it must be falsifiable.
Science is a continuous process of using data to understand the various phenomena of the world. Nothing in the world of science can be considered absolute.
A scientific hypothesis is just a carefully worded statement of an idea that has to then undergo various experiments, and tests and face scientific argumentation in order to be proven valid.
Therefore, a good scientific hypothesis example will be "a certain type of mango has a gene for orange pigment, that mango will be orange coloured".

imagine you are a marine scientits. which of the following organisms would you warn people to avoid eating due to the risk of high levels of toxins in their bodies as a result of biomagnification
A. Algae
B. Phytoplankton
C. Small fish
D. Sharks mom
Eating sharks will be of maximum risk.
Option D.
Explanation:Biomagnification is a phenomenon where a toxin which is present in the environment is taken by smaller organisms and the concentration of toxins increase in concentration in higher tropic levels.
Suppose a toxin is present in sea water. It's taken by the small algae along with water which isn't metabolized by the algae, but stored in their body. Now these algae are consumed by small phytoplankton which consume a lot of algae, and the toxin present in their body, which again gets stored due to no metabolism. This even increases into smaller fishes, larger fishes and then into shark which has the maximum toxin concentration. So consumption of sharks will be of maximum health risk.

Which region in the United States has the fewest thunderstorms per year
Answer: The West coast region has the fewest thunderstorms per year
Explanation: Oregon, Washington, California, Alaska and Hawaii are all examples of states in the west coast region of the United States.
The west coast region having the fewest thunderstorms is due to two main factors which are; coldness of the pacific ocean and the dryness of air in the region (Low humidity). These two conditions doesn't give room for the formation of any thunderstorm activity.
The Pacific Coast of the Pacific Northwest in the United States experiences the fewest thunderstorms per year due to its stable marine environment and the rain shadow effect created by mountain ranges.
Explanation:The region in the United States with the fewest thunderstorms per year is the Pacific Coast of the Pacific Northwest. This area generally experiences less thunderstorm activity due to its proximity to the cool waters of the Pacific Ocean and the stabilizing influence of the marine environment. While the western United States experiences a rain shadow effect due to the presence of mountain ranges, which causes arid and semi-arid lands to the east of the mountains, it is the Pacific Coast itself that is known for milder weather and less frequent thunderstorm events. Of note, areas like the Great Basin and regions east of the Sierra Nevada are also among those with less frequent thunderstorm activity due to their geographic characteristics and prevailing climatic patterns.

D. It proposed that Earth was shaped by the same physical
processes in the past as it is in the present.
Answer:
D is the correct answer not B or c or a.
Explanation
The principle of uniformitarianism, developed by James Hutton, is best described as the concept that the same geological processes shaping Earth today have also shaped it in the past.
Explanation:James Hutton developed the principle of uniformitarianism. The statement that best describes this principle is: D. It proposed that Earth was shaped by the same physical processes in the past as it is in the present. The principle of uniformitarianism asserts that the geological processes we observe shaping the Earth today, like erosion and sedimentation, have worked in much the same way throughout Earth's history. This idea contradicts the view that the Earth's features were formed by sudden, catastrophic events that do not occur in the present. Hutton's concept strongly influenced Charles Lyell, a friend and influence on Charles Darwin, who applied the principle to his theory of evolution, suggesting that slow and gradual changes in species could occur given enough time, much like the geological processes.

How will you prove that the food stored in leaves os starch
Answer:
To prove the food stored in leaves is starch "we will use a iodine indicator, if the leaf turn blue-black then it is confirmed that the leaf has starch. "
Explanation:
To prove the stored food in leaves is starch, first we will take a leaf, then we will treat the leaf in hot water followed by alcohol. The leaf will die when comes in contact with hot water and the alcohol will help us in the break down of the chlorophyll. Which will fade the green color. Now, we will put iodine, which we use as an indicator in the leaf, when it turn blue-black, it is confirmed that starch is present in the leaf. Sometimes the leaf will turn reddish brown, which depicts the absence of starch.
The number of covalent bonds that an atom tends to form is equal to:
A: the number of valence electrons.
B: the number of unbalanced neutrons.
C: the number of unpaired electrons.
D: the atomic number.
E: the number of nearby atoms.
Number of covalent bonds by an atom is equal to number of unpaired electrons.
Explanation:Valency of an atom is defined as the combining capacity of an atom. Valence electrons are defined as the number of electrons in the outermost shell of an atom.
Now for an atom, when more than one electrons are present, then they often forms a pair. Like for example, if there are 7 valence electrons, 6 get as pairs and only one electron is unpaired. So this is why the halogens like fluorine, chlorine etc has the Valency of 1. For oxygen, 4 valence electrons become paired. And rest 2 electrons form 2 covalent bonds.

In your own words Describe how autotrophs and heterotrophs obtain energy. please this answer must be at least 150 words any one will answer it I will mark it as brainliest.
The autotrophs are the primary producer in the food chain and they are the ones who initiate the food chain. They produce food by using sunlight or sometimes chemical energy or reactions. They primarily use carbon dioxide, sunlight and water to form sugars or carbohydrates which become their energy source. They use the process of photosynthesis or chemosynthesis to generate food. Examples of autotrophs are green plants, green algae, bacteria.
Heterotrophs cannot make their food via sunlight or other inorganic sources and hence are dependent on the autotrophs or other animals. The heterotrophs have been ranked as secondary and tertiary consumers and cannot be producers. They consume the organic products made by autotrophs to obtain energy for various metabolic and biological activities. The heterotrophs can be herbivore, carnivore, fungi, parasitic plants.
Some are photo-hetrotrophs, who use light as energy but cannot use carbon dioxide as the carbon source since they cannot fix the carbon like autotrophs.
