Explain how roots hair cells use osmosis to take up water.
Answer:
Plants absorb water from the soil by osmosis. They absorb mineral ions by active transport, against the concentration gradient. Root hair cells are adapted for taking up water and mineral ions by having a large surface area to increase the rate of absorption.

Give two uses of energy transferred by respiration in eukaryotes
Answer:
Most aerobic respiration takes place inside mitochondria. Some of the energy released in respiration is used to make larger molecules from smaller ones, to enable muscles to contract and to keep temperature steady. Some of the energy released in respiration in plants is used to make amino acids and proteins.
Explanation:google said it and i had this question in my science class and got it right
The uses of energy are - energy for metabolic reaction and growth and development of cells.
Cellular respiration provides energy with the series of complex chemical reaction cycles that is used for:
Working your muscles - for movement and physical activities energy is required.Growth and repair of cells - dividing cells, repairing them and development of the cells also require energy.Building larger molecules from smaller ones for instance proteins from amino acids.Allowing chemical reactions to take place.Absorbing molecules in active transport.Thus, The uses of energy are - energy for metabolic reaction and growth and development of cells.

Why is protein synthesis different in prokaryotes and eukaryotes
Answer:
A few aspects of protein synthesis are actually less complex in eukaryotes. In prokaryotes, mRNA is polycistronic and may carry several genes that are translated to give several proteins. In eukaryotes, each mRNA is monocistronic and carries only a single gene, which is translated into a single protein.

Which statements describe oceanic crust? Select the two correct answers.
A. It’s age ranges from very young to more than 4 billion years old.
B. It is formed at zones of volcanic activity on the ocean floor.
C. It is made of all types of rocks.
D. It is between 25 and 70 km thick.
E. It contains silicate minerals high in iron and magnesium.
Answer:
The correct answers are options B. "It is formed at zones of volcanic activity on the ocean floor. ", C. "It is made of all types of rocks" and E. "It contains silicate minerals high in iron and magnesium."
Explanation:
In Geology, the continental crust is defined as the layer of the Earth that allowed the formation of the continents. This layer is made of all types of rocks, including igneous, metamorphic, and sedimentary rocks. This layer is also considered silica-rich, or felsic, because of its high content of silicate minerals. Regarding the thickness of continental crust, it is between 25 to 70 km thick. This is considerable thick considering that oceanic crust which barely reaches 10 km thick.

Answer:
In humans, a zygote will develop into a female if the sperm that fertilizes the egg has an X sex chromosome.
Explanation:
The sex chromosomes contributed by the man are sexual determinants, since his gametes —sperms— possess both the X and Y sex chromosomes. In contrast, the eggs only possess the X sex chromosomes.
Male XYFemale XXIf an egg is fertilized by a sperm carrying the X sex chromosome, the zygote will have one pair of X chromosomes that will determine the female sex in the product.
Identify the types of signals which sensory receptors can detect.
Thanks:)
Answer:
Explanation:
Sensory receptors can be classified by the type of stimulus that generates a response in the receptor. Broadly, sensory receptors respond to one of four primary stimuli:
Chemicals (chemoreceptors)
Temperature (thermoreceptors)
Pressure (mechanoreceptors)
Light (photoreceptors)

How does competition shape communities?
Answer:
In the short term, what we would call “ecological time scales”, competition shapes communities primarily by limiting population growth. Every population requires and excess of required resources to grow larger, but if another population is taking those resources instead, then their growth is limited. If your competitor is significantly better at securing resources, and is growing larger, your population may find that it is actually too large for the amount of resources it is capable of obtaining, and so will have to shrink down to a level that can be sustained by the amount of resources it can get.
Competition with individuals of your own species also limits the size of your population, even more so than competition with other species. This is because members of the same species have more overlapping sets of resources that they require. Two humans both need houses and water, so they compete for them both, but they don’t have to compete with birds for houses, only water.
In the longer term, called “evolutionary time scales”, competition can change the characteristics of the species that are in competition with each other. Species may evolve to need certain resources less if their competitors are better at obtaining them. This allows those two species to evolve to be more compatible, allowing them to better coexist by making them less competitive with one another.
Evolution won’t change a single species to be able to compete less with members of its own species, but in some cases it can lead to the creation of new species.

How does mitochondria help the cell get the material it needs
Answer:
Known as the “powerhouses of the cell,” mitochondria produce the energy necessary for the cell's survival and functioning. Through a series of chemical reactions, mitochondria break down glucose into an energy molecule known as adenosine triphosphate (ATP), which is used to fuel various other cellular processes.

Describe how radiocarbon dating method is used to find the absolute age of a fossil?
Answer:
Radiocarbon dating involves finding the age of an ancient fossil by measuring its carbon-14 content. Carbon-14 (radiocarbon), is a naturally occurring radioactive isotope that forms when cosmic rays in the upper atmosphere strike nitrogen molecules, which then oxidize to become carbon dioxide.
