Answer:
Replication
Explanation:
DNA unwinds into 2 seperate strands during replication
DNA replication is the process in which DNA makes it copy and incorporate into the daughter cell. Cell division is the process in which the DNA is replicated and transmitted in the daughter cells.
DNA replication is the starts with the formation of a replication fork, in which the helical structure of the DNA is unwinded into two template strands.
The information coded into the template strand is copied into the complementary strand. The process of making a complementary strand from the template strand involves transcription, followed by a translation.
Thus, during cell division, the DNA is replicated and separated into two strands.

Plants absorb nitrogen from: the atmosphere the soil water
Answer:
Plants absorb nitrogen from: the soil ( second choice)
ANSWER:
Plants absorb nitrogen from the soil.
EXPLANATION:
Nitrogen is absorbed by the roots of the plants in the form of amino acids, nitrate or nitrite ions. The nitrogen absorbed from the soil by roots is then transported to the various parts of the plants. Plants do not get nitrogen they need directly from the air. This is because the organic nitrogen that is available in the atmosphere is not usable for plants. Plants need non-organic nitrogen which is obtained by changing organic nitrogen into non-organic forms by the bacteria in the soil.why do sex linked traits follow different patterns of inheritance than other traits

When did oxygen levels start to decline from 35 percent down to today's levels during what period
about 95 million years ago, during the Carboniferous Period
Answer:
During Carboniferous period, part of the late Paleozoic era.
Explanation:
In the geological story oxygen levels have been relatively stable for the las 200 million of years, but 300 million ago there was a dramatic spike in Oxygen levels until 35% in the Carboniferous , next it plunged in 15 percent in the Triassic, 100 million years later. The growth of the forests removed huge amounts of carbon dioxide from the atmosphere, leading to a surplus of oxygen. The higher oxygen concentration is related with the presence of larger bodies in reptile and insects.
Brianna’s doctors advise her to eat no more than 30 grams of carbohydrates per day for her snacks. Because dietary fiber doesn’t negatively affect blood sugar levels, she doesn’t need to count it toward her carbohydrate total. If Brianna eats two servings of each of these foods, will she fall under her doctor’s recommended limit for her snack? Explain your reasoning.
Answer:
No, her dietary consumption won’t fall under the recommended limit. Subtracting fiber, there are 11 grams of carbohydrates per serving in the first snack and 5 grams per serving for the second snack. If she eats two servings of each snack, she’ll consume 32 grams of carbohydrates.
Explanation:
The details given are not enough to determine whether Brianna will fall within the advised carbohydrate limit. This requires knowledge of the carbohydrate content of her snack servings. However, it is essential to note that while carbohydrates are the body's primary energy source, they need to be consumed in moderation.
Explanation:The details provided in the question are not sufficient to determine whether Brianna will fall under her doctor's recommended limit for her snack. To arrive at the correct conclusion, you need to know the amount of carbohydrates, not including fiber, in every serving of the snacks Brianna intends to consume.

Jasmine, at 33 months of age, is able to engage in some self-care behaviors but still has trouble with tasks such as putting on socks. A few months later, she accomplishes this same task relatively easily. The change in abilities is most likely due to _____.
Answer:
Developmental progression of functional skills
Explanation:
With the passage of time, a kid not only grows physically and mentally but also in his/ her cognitive abilities to perceive and understand the happening around him. He develops a a relationship sense for peers, family members and related adults. Similarly, he also develops the ability to learn the things which are quite basic for us like taking off clothing items.
These things come under the umbrella of developmental progression for functional skills. studies have shown that a kid learns to take off clothing items before he learns to put them on. Same is the case with putting on socks, a kid can take off socks by the age of 12 months which is earlier than he learns to put them off (age of 18 months) with the assistance of any elder and independently by the age of almost 4 years.
This developmental progression helps a kid to modify his behavior and to be more independent.
Hope it helps!
The change in Jasmine's abilities, progressing from struggling with tasks like putting on socks at 33 months to accomplishing them relatively easily a few months later, is most likely due to:
A. fine motor skills.
As Jasmine grows and her fine motor skills develop, she becomes more adept at tasks like putting on socks, demonstrating improved coordination and control over her movements. This developmental progression allows her to accomplish previously challenging tasks with greater ease and proficiency.
The change in Jasmine's abilities, progressing from struggling with tasks like putting on socks at 33 months to accomplishing them relatively easily a few months later, is most likely due to her developing fine motor skills. At 33 months, children are still refining their coordination and dexterity, making tasks like putting on socks challenging. However, with continued practice and maturation, Jasmine's fine motor skills improve, allowing her to perform tasks requiring precise hand movements more effectively. This developmental progression is typical as children grow, and their neurological pathways strengthen. The newfound ability to put on socks relatively easily demonstrates Jasmine's enhanced fine motor control and highlights the importance of developmental milestones in acquiring self-care abilities.
The correct question is:
Jasmine, at 33 months of age, is able to engage in some self-care behaviors but still has trouble with tasks such as putting on socks. A few months later, she accomplishes this same task relatively easily. The change in abilities is most likely due to _____.

18. In replication of DNA, the helix is opened and what is unzipped?
A. Nitrogen bond
C. Oxygen bond
B. Hydrogen bond D. Phosphate bond
Answer:
B) Hydrogen Bond
Explanation:
Those are the bonds that the restrictive enzymes unzip and the bonds that hold the complementary bases.
Final answer:
In DNA replication, helicases unzip the DNA molecule by breaking the hydrogen bonds between the nitrogenous base pairs.
Explanation:
DNA replication is a process that involves the unzipping of the DNA molecule. During this process, enzymes known as helicases break the hydrogen bonds between nitrogenous base pairs. This action separates the two strands of the DNA double helix and allows each strand to serve as a template for the creation of a new complementary strand. Consequently, the letter corresponding to the correct answer is B. Hydrogen bonds between complementary bases break during the replication of DNA.

which consumers live in the open ocean
Answer: swordfish, dolphins, and sharks
Explanation: Consumers must eat other consumers or producers to survive in the open ocean. Out of the provided answer choices, swordfish, dolphins, and sharks all prey on producers or other consumers to eat.
In the oceanic zone, primary consumers include plankton, with larger predators like whales and dolphins feeding on them. Nutrients are scarce, and the food web complexity decreases with depth. Overfishing has significantly impacted populations of large fish and marine mammals.
Explanation:The open ocean, also known as the oceanic zone, is a marine biome characterized by thermal stratification where warm and cold waters mix due to ocean currents. This zone hosts a variety of consumers, including plankton, which form the base of the food chain, and larger animals such as whales and dolphins that feed on them. Due to the scarcity of nutrients, the oceanic zone is less productive compared to coastal regions. Nonetheless, it supports a diverse array of life forms adapted to this environment.
Photosynthetic organisms are predominantly found in the upper layers where sunlight penetrates, forming the basis for the food chain. When these organisms die, they fall to the ocean floor, providing nutrients for bottom-dwelling creatures in the aphotic zone, such as sea cucumbers. Notable is the absence of a mechanism to recycle nutrients back to the surface in the open ocean, except in areas of upwelling.
Over-exploitation and certain fishing practices have led to dramatic declines in the populations of large fish and marine mammals, which are key components in the ocean's complex food webs.

What are the end products of the light-dependent reactions that need the presence of light to occur?
The end products of the light-dependent reactions, which require light to occur, are ATP and NADPH. These molecules are then used to power the light-independent reactions (Calvin Cycle) where glucose is synthesized.
The light-dependent reactions of photosynthesis are the initial phase where light energy is converted into chemical energy. Specifically, these reactions take place in the thylakoid membranes located within the chloroplasts. The primary function of the light-dependent reactions is to produce energy-rich molecules, which are ATP (adenosine triphosphate) and NADPH (nicotinamide adenine dinucleotide phosphate). These molecules are essential to power the subsequent process, known as the light-independent reactions or the Calvin Cycle.
The overall summary of the light-dependent reactions can be represented as:
12 H₂O + 12 NADP⁺ + 18 ADP + 18 [tex]P_i[/tex] + light → 6 O₂ + 12 NADPH + 18 ATP
In essence, water (H₂O) is split in the presence of light, releasing oxygen (O₂), which is a by-product. The main products, ATP and NADPH, are then utilized in the light-independent reactions to synthesize glucose and other carbohydrates from carbon dioxide (CO₂) and water (H₂O).

Explanation:
The points of muscle attachment are known as the
Answer:
Origin and Insertion
Explanation:
The origin is the point of attachment of a muscle that remains relatively fixed during contraction.
The insertion is the point or mode of attachment of a skeletal muscle to the bone or other body part that it moves.
Muscle attachment points are known as the origin and the insertion. The origin is the fixed end attached to a stabilized bone, while the insertion is the movable end which attaches to the bone being pulled. These points of attachment are critical in enabling muscle movements.
Explanation:The points of muscle attachment are known as the origin and the insertion. The origin is the end of the muscle that attaches to a fixed, or stabilized, bone. The insertion is the moveable end of the muscle that attaches to the bone being pulled. These terms are used when discussing skeletal muscles and how they interact with our skeleton to enable movement.
An interesting point to note is that often the name of a muscle can indicate its points of attachment. An example of this is the sternocleidomastoid muscle of the neck, which originates on the sternum (sterno) and clavicle (cleido), and inserts onto the mastoid process of the temporal bone.
Attached muscles are primarily responsible for movements, with the prime mover being the muscle mainly involved in a specific movement, and synergist muscles offering supportive help to the main muscle.
The points of muscle attachment are called origin and insertion. The origin is the end of the muscle attached to a fixed bone, while the insertion is the end of the muscle attached to the bone being pulled. For example, in the forearm flexion movement, the brachioradialis assists the brachialis muscle as a synergist.
