Which component of the cell membrane participates in this process?
A. Phospholipid bilayer
B. Carbohydrate chains
Facilitated Diffusion
C. Protein channels
Outside of cell
D. Fatty acid tails
mann
W
W
Inside of cell
Answer:
Explanation:
A cell membrane is composed of two phospholipid layers in which each molecule contains a single phosphate head and two lipid, or fatty acid, tails. The heads align along the inner and outer boundaries of the cell membrane, while the tails occupy the space in between. Only small, nonpolar molecules can pass through the membrane through simple diffusion. The lipid tails reject polar, or partially charged, molecules, which include many water-soluble substances such as glucose. However, the cell membrane is peppered with transmembrane proteins that provide passage to molecules that the tails would otherwise block.

Vertebrates comprise all animal taxa within the subphylum Vertebrata, including all mammals, birds, reptiles, amphibians, and fish.
What is meant by vertebrates?Vertebrates comprise all animal taxa within the subphylum Vertebrata, including all mammals, birds, reptiles, amphibians, and fish. With approximately 69,963 species currently known, the phylum Chordata is dominated by vertebrates.
Animals with internal backbones are known as vertebrates. Fish, amphibians, reptiles, birds, and mammals are among the major groups. None of the invertebrates have a backbone. Like worms and jellyfish, they either have a soft body, or creatures like spiders and crabs have a hard shell that surrounds their body.
Therefore, the correct answer is as follows:
1: b) have an internal skeleton but not a backbone or spinal column.
2: d) multicellular, ectothermic, vertebrate
3: a) Mammal

Landslide is an inevitable process in hilly areas. Do you agree with this statement? Why?
Answer:
In hilly areas, the landforms are generally sloped and heavy rainfall loosens the material. When the right combination of materials, moisture, and steepened slope angle (i.e. increased gravity) makes a hillside unstable, a slide or flow is inevitable.

Answer:
A mutation is a change in the nucleotide sequence of the DNA in a cell. ... Mutations can occur before, during, and after mitosis and meiosis. If a mutation occurs in cells that will make gametes by meiosis or during meiosis itself, it can be passed on to offspring and contribute to the genetic variability of the population.

Which hormone is responsible for the development of the male secondary sex characteristics?
O estrogen
O progestin
O progesterone
testosterone
The answer is D on 2021 edge :)
Answer:
Testosterone
Explanation:
The hormone that is responsible for the development of the male secondary sex characteristics is testosterone, which is the last option as testosterone is a steroid hormone produced primarily in the testes of males.
What is the significance of testosterone in males?Testosterone plays a crucial role in the development and maintenance of male sexual characteristics that have positive influence on body. It induces the development of sperm, and in puberty, it triggers the development of the male secondary sexual characteristics, which affect many aspects of male health and well-being, including bone density, so testosterone is important.
Hence, the hormone that is responsible for the development of the male secondary sex characteristics is testosterone, which is the last option as testosterone is a steroid hormone produced primarily in the testes of males.

a. What type of organism is the grass?
Answer: it’s a producer
Explanation: The grass is a producer because it produces food while other animals get food themselves.
The grass is the producer of the food chain. Producers are the organisms in the food chain which produce food in a food chain.
What are the producers in a food chain?Producers are the organisms which make their own food in a food chain through photosynthesis. Producers are also known as autotrophs. They get energy to work from the chemicals or the sunlight, and with the help of water, these organisms convert the light energy into useable energy that is the chemical energy in the form of sugar or food particles. The most common example of a producer are the green plants.
Producers are any kind of green plants. Green plants make their food by taking sunlight and using this energy to make glucose (carbohydrate). The plant uses this carbohydrate, also called glucose to synthesize many products, such as wood, leaves, roots, and bark. Grasses are also an example of producers in a food chain as they produce glucose.

What are the two types and functions of vascular tissue?
Answer:
Vascular tissue transports water, minerals, and sugars to different parts of the plant. Vascular tissue is made of two specialized conducting tissues: xylem and phloem. Xylem tissue transports water and nutrients from the roots to different parts of the plant, and also plays a role in structural support in the stem. Phloem tissue transports organic compounds from the site of photosynthesis to other parts of the plant. The xylem and phloem always lie adjacent to each other in a vascular bundle

What are non-renewable resources?Using bicycles instead of driving cars is an environmentally friendly choice because it helps reduce the consumption of non-renewable resources, such as fossil fuels, as fossil fuels are a limited resource that takes millions of years to form and their use contributes to air pollution and greenhouse gas emissions, which are major contributors to climate change. In addition to the environmental benefits, cycling can also have positive health impacts. Regular cycling can help improve cardiovascular health and reduce the risk of chronic diseases such as obesity and diabetes.

He decides to design an experiment based on this information. Gavin uses an empty shoe box, a sheet of paper towel, and tape to build a model of a spacecraft. Then, he shoots a pea at the paper towel part of the model using a straw pea shooter. For his first trial, Gavin shoots a 3.0-gram pea at the model. Its speed is measured at 12 meters per second as it leaves the straw. The pea does not break the paper towel, but it bounces back off and lands on the ground.eds that they can damage or puncture the sides of space vehicles.
