What can you tell about an igneous rock that has a coarse-texture?
A. It is a carbonate.
B. It probably formed in a volcanic eruption.
C. It is most likely formed underground.
D. It is extrusive.
Answer: It is most likely formed underground
An igneous rock that has a coarse texture is one that formed from slowly cooling magma deep within the Earth's crust, or from slowly cooling lava on the surface. The slow cooling allows large mineral crystals to grow, giving the rock a coarse, grainy texture.
What can the size and shape determine ?The size and shape of the mineral crystals within the rock can provide information about the rock's cooling history and the conditions under which it formed. Coarse-grained igneous rocks such as granite, gabbro, and diorite typically have crystals that are visible to the open eye, with sizes ranging from a few millimeters to several centimeters in diameter.
The composition of the rock can also be determined based on the types of minerals present in the coarse-grained texture. For example, if the rock contains primarily feldspar and quartz, it is likely a granite. If it contains mainly plagioclase feldspar and pyroxene, it is likely a gabbro.
Overall, the coarse texture of an igneous rock indicates that it cooled slowly over a long period, allowing mineral crystals to grow and form a visible grain structure. The size and composition of the crystals can provide clues about the rock's history and origin.

Make me brainliest pls
The term that is used to describe the number of deer in a square kilometer of forest is population density.
What is population density?
Population density is a measure of how crowded or dispersed a population is in a particular area. It is calculated as the number of individuals of a particular species per unit of area, such as square kilometer or square mile. This measure helps to understand the concentration of individuals of a species in a given area. A high population density means there are more individuals of a species per unit area, whereas a low population density indicates fewer individuals in a given area.
Population density plays a crucial role in understanding and predicting the effects of population growth on the environment. High population density can lead to increased competition for resources such as food, water, and shelter, which can cause stress on the ecosystem. It can also lead to an increased risk of diseases and higher rates of pollution. In contrast, low population densities can lead to the extinction of species due to lack of genetic diversity and inbreeding. Understanding population density is important for conservation biology, urban planning, and resource management, among others.

What is the purpose of using a Punnett square in studying genetics?
A. to determine the probability of an offspring to breed with another of the same phenotype
B. to determine the exact number of offspring having a particular genotype
C. to determine the probability of an offspring having a particular phenotype
D.to determine the probability of an offspring having a particular genotype
The purpose of using a Punnett square in studying genetics is to determine the probability of an offspring having a particular genotype. Thus, the correct option for this question is D.
What is Punnett square?Punnett square may be defined as a type of table in which all of the possible outcomes for a genetic cross between two individuals with known genotypes are determined. It is named after Reginald C. Punnett, who proposed this approach in 1905.
In genetics, Punnett square is extremely utilized in order to predict the possible outcomes of two unknown genotypes. With the help of these genotypes, phenotypes of a specific set of alleles are also determined. The important concept of Punnett square is that it always determines the probability, not the exact number.
Therefore, to determine the probability of an offspring having a particular genotype is the purpose of using a Punnett square in studying genetics. Thus, the correct option for this question is D.

A. Their zygotes undergo changes to turn into a blastula.
B. Human cells have cell walls and are unable to move.
C. Humans can reproduce asexually when under stress,
D. Animals and humans are both uni-cellular organisms.
Answer:
It's A
Explanation:
Had it on a test
Humans are considered animals because as in animals zygotes after cell division turns into a blastula, hence option a is correct.
What are animals?More than any other species, humans are capable of learning new things. Indeed, the majority, but not fully, of what distinguishes us from other animals is anchored in language.
In addition, because we have a backbone, humans are considered to be members of the chordate animal phylum.
The zygote is split into the blastula after fertilization, three germ layers develop in the blastula, which in some species is a hollow ball of cells, during a process known as gastrulation.
Therefore, humans are classified as members of the primate order within the animal group and having the blastula stage, hence option a is correct.

If you are interested in the evolutionary relationship of animals that have four limbs, which of the following would be the outgroup? Group of answer choices Sharks Ray-Finned Fish Amphibians Crocodiles Dinosaurs
Answer:
First outgroup → Ray-Finned FishesSecond outgroup → SharksExplanation:
The outgroup is the most distant taxonomic group that shares no traits or characters with the lineages of interest, which compose the ingroup. You can compare the outgroup with the ingroup to determine the evolutive relationship and which characters are primitive or derived.
Even though the outgroup shares a common ancestor with the ingroup, this is placed far away in evolution, making the outgroup to be the taxonomic group less related to the other lineages. The lineages in the ingroup share another common ancestor that is more recent in history.
To select the outgroup, you need to focus on what you are interested in. There might be several outgroups, but you should choose the one that is more related or closer to the ingroups. This selection is important because you need to make comparisons to understand the evolution of specific traits.
In the exposed example, we need to focus on animals that have four limbs. Then, we might assume that the ingroup is composed of Amphibians Crocodiles Dinosaurs. Sharks and Ray-Finned Fish do not have four limbs, so they might be considered outgroups.
From these two outgroups, sharks have a cartilaginous skeleton, while Ray-Finned Fishes have a bony skeleton. This fact makes ray-finned fishes more related to the ingroup than the sharks. So,
First outgroup → Ray-Finned FishesSecond outgroup → SharksWhat are the characteristics of annelidas

THE BIG IDEA ALL LIVING THINGS SHARE COMMON TRAITS Activity 1: Lesson introduction
CONSIDER AND CONNECT
DIRECTIONS: After reading the lesson introduction below, complete the activity by answering the questions that follow.
Think about the last time you ate a bowl of cereal. Maybe it was this morning, or months but if you concentrate you will remember the experience. Close your eyes and get a mental picture of yourself eating and tasting the cereal. Describe in as much detail as possible what you remember about the last time you ate cereal. Include what type of cereal you ate as well as the dishes you used or the room in which you enjoyed your meal.
Most likely your response involved eating cereal in a bowl, and with a spoon.
1. How would your experience of eating cereal.
have been different if you would have used a plate instead of a bowl and a fork instead of a spoon?
2. Why do you think that we have different dishes and utensils to eat different foods?
In the same way that your kitchen uses different items, like pots, plates, or utensils, your body has different parts to perform different functions. The way a part looks often relates to what it does. For example I cannot bake a cake by putting it in the refrigerator because the refrigerator has parts that make it cold not hot! This idea that structure, or how something is made and looks, relates directly to its function, or the job that it does, is just one of the unifying themes of biology that you will learn about in this lesson. By understanding the basic principles of life and what it means to be "living" you will be able to relate complex concepts throughout all areas of biology. The unifying themes can help simplify these concepts keeping you focused and connected.
Answer:
1) We would not enjoy our breakfast. It just wouldn't be the same. The way a part looks often relates to what it does. For example soup is a liquid yet we do not drink soup from a water bottle.
2)The idea is that structure, or how something is made and looks, relates directly to its function. When we look at the various eateries in our kitchen we immediately know how it is served and the way it tastes.
When we look at the different utensils in our kitchen, we immediately understand their function.

Which is the best definition of directional selection?
a process by which two species can no longer reproduce
a process by which one of the extreme variations of a trait is favored
a process by which individuals with either extreme of a trait are favored
a process by which average individuals in a population are favored
Answer:
B. a process by which one of the extreme variations of a trait is favored
Explanation:
The graph for this type of selection looks sort of like a camel's hump. With that being said, the phenotype of a population experiencing directional selection goes from one extreme to the other. Reference the evolution of the peppered moth during the Industrial Age as an example.
Sincerely hope this helps! God bless!A process by which one of the extreme variations of a trait is favored best describes the directional selection. Therefore, option (B) is correct.
What do you mean by directional selection?Directional selection is a negative natural selection mode in which an extreme phenotype is preferred over other phenotypes, causing the allele frequency to shift over time in that phenotype's favor.
Fossil evidence suggests that while the size of European black bears decreased during interglacial periods of the ice ages, it increased during each glacial period. This is an example of directional selection. A further illustration is the size of a population of finches' beaks.
The behavioral trait in question experiences a concentration of increasing alleles in the line selected in the upward direction and a concentration of decreasing alleles in the line selected in the downward direction.

Describe how pollution can cause acid rain, and how acid rain affects the ecosystems of surrounding areas?
Pollution specifically air pollution can cause acid. Gases such as sulphur (IV) oxide and Nitrogen (IV) oxide when they are released into the atmosphere and comes into contact with precipitation, that is rain water causes acid rain. Sulphurous acid and Nitric acid is formed thus the rain falls in acidic form.
Acid rain when it falls on the leaves of the flora (plants) causes removal of the green colouring matter (chlorophyll) thus making plants to be deficient of food. Food in plants is made my the process of photosynthesis, removal of chlorophyll in plants kills them due to lack of food.
Also when acid rain finds it's way into the water bodies through surface runoff, aquatic animals such as fishes die due to lack of favourable environment and oxygen deficiency in water. Acidity in the soil also kills important decomposers therefore soil aeration is altered.
A diagram shows a potato producing new tubers. Buds on the parent plant grow into stems that grow downwards called stolons. The end of each stolon develop in to new tuber.
1) Give two pieces of evidence which show that this is an asexual method of reproduction.
2) Explain why all the new tubers will be genetically identical.
Answer:
See the answer below
Explanation:
Evidence that shows that the illustration is an asexual method of reproduction:
1. New tubers were produced without any signs of flowering or fertilization
2. Parent plant was produced from a vegetative part ( a tuber).
All the new tubers would be genetically identical because they were produced without fertilization. They all developed from the division of some of the vegetative cells (mitosis) of the parent plant. Hence, they are not only genetically identical with themselves but also with the old tuber that produced the parent plant.

Transfer RNA has __________ bases attached to one end of the molecule and an amino acid to the other.
Answer:
Nitrogenous
Explanation:
Transfer RNA, also known as tRNA, is one of the three types of RNA. It is involved in the translation process. The shape of the tRNA allows it to be a very important component of the translation process.
The morphological structure of the tRNA is in such a way that a sequence of nitrogenous bases called ANTICODON attach to one of its ends while an amino acid is attached to the other end. This way the tRNA molecule is able to read the mRNA codon using its anticodons and carry the corresponding amino acids.
N.B; the anticodons are composed of three nitrogenous bases just like codons. Codons are complementary to anticodons.
