Differences in traits such as hair texture are determined by differences in ? A) The location of sugar groups in DNA B)the sequence of nucleotides in DNA C) The number of nitrogenous bases un DNA D)The molecules attached to the phosphate in DNA
Answer:
A
Explanation:
This is called the locus and is determined in Meiosis by gametes from parent cells. During meiosis there is this thing called 'crossing over' where the gametes (sperm and egg cells) homologous genes (genes of similar size and shape, such as X and Y chromosomes or X and X) exchange genes on the same locus to provide slightly different characteristics.
Please check this with your teacher but i believe that this is right. Hope this helps. ;)

José is learning about the fossil record. He knows the fossil record is the total number of fossils and their locations and that they provide information about an organism that once lived. Which of the following can José gather from studying the fossil record and its evidence?
WILL GIVE BRAINLYEST
Answer:
Similarities between past and present species
Explanation:
Final answer:
José can learn about evolution in detail from the fossil record, understanding the progression and transformation of life over millions of years and gathering evidence for how species have evolved.
Explanation:
Understanding the Fossil Record
Through studying the fossil record, José can learn about the progression of life and the evidence for evolution. By analyzing fossils, which are the preserved remains or traces of organisms, scientists can paint a picture of what life looked like millions of years ago. This helps us understand how species are related, how they have changed over time, and when they lived. For instance, the comparison of the morphology of a whale flipper with that of bird and mammal appendages can provide evidence of a common ancestor, illustrating the concept of evolutionary change over time.
Fossils provide solid evidence that past organisms are distinct from those found today. The detailed records of fossils, such as those of humans and horses, show evolutionary adaptations and transformations, revealing a history of life that has spanned over four billion years. José can infer the characteristics of extinct species and comprehend the immense time scale involved in the evolutionary process.

Review Answer Selections
Answer:
D
Explanation:
DNA pairs with adenosine, thymine, cytosine, and guanine
RNA pairs with uracil, adenosine, cytosine, and guanine
Option D is correct because RNA pairs uracil with adenine instead of thymine, unlike DNA. Other differences include ribose in RNA versus deoxyribose in DNA and RNA being single-stranded while DNA is double-stranded.
The correct answer to the question is Option D: pairs uracil with adenosine instead of thymine.
A. has deoxyribose as the sugar within its nucleotide components: This statement is incorrect because RNA contains ribose, not deoxyribose. Deoxyribose is found in DNA.B. contains two strands wrapped in a helix: This is incorrect because RNA is typically single-stranded, whereas DNA is double-stranded.C. contains nitrogenous bases: While this is true for both RNA and DNA, it does not 'unlike' DNA. Both types of nucleic acids contain nitrogenous bases.D. pairs uracil with adenosine instead of thymine: This is the correct statement. Unlike DNA, RNA uses uracil in place of thymine and pairs it with adenine.In summary, RNA and DNA differ primarily in their sugars (ribose vs. deoxyribose), the presence of uracil instead of thymine, and RNA being single-stranded compared to the double-stranded DNA.

Andreas has to make an electromagnet in his science class. He was only given a nail, copper wire, and a 9-volt battery. The assignment was to make a magnet strong enough to pick up paper clips. His teacher decided to make the assignment into a competition to see whose magnet could pick up the most clips.
What can Andreas do to his magnet to make sure he wins by picking up the most paper clips?
A
Andreas can wrap few coils of the wire, far apart, around the nail.
B
Andreas can wrap many coils of the wire, far apart, around the nail.
C
Andreas can wrap many coils of the wire, close together, around the nail.
D
Andreas can wrap few coils of the wire, close together, around the nail.
Answer:
C. Andreas can wrap many coils of the wire, close together, around the nail.
Explanation:
The ideal in this case is for Andreas to wrap the entire nail with the wire. For that he will need to use many coils of the thread. These coils should be close together, touching each other, but without overlapping, they should be next to each other. That way, Andreas's experiment will work.
If he wants to increase the magnetism power of his electromagnet, he must replace the battery with a higher voltage one.

Explain how a cold front is formed.
Explanation:
Cold fronts form when a cooler air mass moves into an area of warmer air in the wake of a developing extratropical cyclone. The warmer air interacts with the cooler air mass along the boundary, and usually produces precipitation. Cold fronts often follow a warm front or squall line.
Cold Front: transition zone from warm air to cold air. A cold front is defined as the transition zone where a cold air mass is replacing a warmer air mass. Cold fronts generally move from northwest to southeast. The air behind a cold front is noticeably colder and drier than the air ahead of it.

What’s the difference between a red deer, roe deer, chamois, and ibex?
Answer: Male ibex, red deer, and roe deer were generally harvested at higher elevations compared to females, whereas female chamois were harvested at higher elevations compared to male chamois. Differences in harvest elevations between males (higher) and females (lower) are smallest for ibex and largest for red deer.
Explanation: Hoped this helped
The red deer is large with prominent antlers, while the smaller roe deer has shorter antlers. The chamois is well adapted to mountains with a robust body and short horns, and the ibex is notable for its large, curved horns and mountainous habitat preference. Human activities have influenced their populations and distributions.
Differences Between Red Deer, Roe Deer, Chamois, and Ibex
The red deer, roe deer, chamois, and ibex are distinct species with unique characteristics. The red deer is known for its size and imposing antlers, especially during the rutting season when the stags roar to assert dominance. Roe deer, by contrast, are considerably smaller, with shorter antlers and more solitary behavior. Chamois are adapted to mountainous terrain, with a robust body and shorter horns that hook backwards. Lastly, the ibex is recognized for its large backward-curving horns and is typically found in rocky, mountainous environments.
Each species occupies a different ecological niche and has distinct adaptations that assist in survival, such as the chamois' agility in rugged terrain and the ibex's ability to scale steep cliffs. All of these species have been affected by human activities, ranging from hunting to habitat changes, impacting their populations and distribution.

The sierra Nevada mountains are made from...
A Mafic igneous intrusive rock
B felsic igneous extrusive rock
C felsic igneous intrusive rock
D Mafic igneous extrusive rock
PLEASE HELP ASAPPPP
The Sierra Nevada mountains are made from felsic igneous intrusive rock, specifically granite, which is formed from slow-cooling magma beneath Earth's surface.
Explanation:The Sierra Nevada mountains are composed principally of felsic igneous intrusive rock. This felsic composition is rich in light-colored minerals such as feldspar and quartz, which indicate that the rock is granite in nature. The formation process involves magma cooling slowly beneath the Earth's surface, allowing time for larger crystals to develop, which gives the rock a coarse-grained texture. Therefore, the correct answer to which type of rock the Sierra Nevada mountains are made from is option C: felsic igneous intrusive rock.

We could call this a wetland community. Compare this community to an ecosystem. Differentiate one more important difference between the organization of the two?
Interactions in a community occur only between living creatures or biotic components. Interactions take place in an ecosystem between living components as well as between non - living and living components.
What is a wetland community?Wetland communities are aggregations of individuals from various species (plants, animals, microorganisms) that live and interact in habitats with water at or near the ground's surface or where the land is inundated by shallow water for large portions of the year.
Wetlands are locations where water covers the soil or is present at or near the soil's surface all year or for a variety of times throughout the year, including the growing season.
In a community, interactions occur between only biological organisms or biotic components.
Interactions occur in an ecosystem between living and non-living components as well as between living and non-living components.

function of diastema in herbivores
Answer:
Gnawing and chewing of plants.
Explanation:
Diastema are spaces found in the dentition of most mammals or any organism that has teeth. It is a space separating dentition for different functions, specially that amongst the biting tooth and grinding tooth. Rabbits are been used as a case study because they are herbivores and also don't have canines, so the diastema helps with gnawing and chewing of plants.
It is well known according to study that a great number of herbivores have no canine, so the diastema aids in holding, gnawing and chewing of plants. This is really helpful, considering rabbits are herbivores.

deoxygenated blood obtains oxygen from the
Answer:
Lungs.
Explanation:
Deoxygenated blood contains high amount of carbondioxide while oxygenated blood has oxygen in large concentration. This carbondioxide is produced in the cell in the process of cellular respiration. This deoxygenated blood is taken from the cell to the lungs through the veins. In the lungs, the carbondioxide is removed and oxygen is loaded in the blood. This oxygenated blood is again goes to the heart and distributed to all the cells.

gravitational pull? *
O
an asteroid
Earth
O
the Moon
O
the Sun
The greater the mass of an object, the greater its gravitational pull on other objects around it. Sun exerts the greatest gravitational pull.
What do you mean by gravitational pull?Gravity is a force which tries to pull two objects toward each other. Anything which has mass also has a gravitational pull. The more massive an object is, the stronger its gravitational pull is. Earth's gravity is what keeps you on the ground and what causes objects to fall.
The reason gravity pulls you toward the ground is that all objects with mass, like our Earth, actually bend and curve the fabric of the universe, called spacetime. That curvature is what you feel as gravity.
On Earth, gravity pulls all objects "downward" toward the center of the planet. According to Sir Isaac Newton's Universal Law of Gravitation, the gravitational attraction between two bodies is stronger when the masses of the objects are greater and closer together.
