Help asap !!!! Which of these statements is true of the brightest stars? (1 point)
O They are yellow stars.
O Many are supergiants
O Several are white dwarfs.
O Each is part of the main sequence.

Answers

Answer 1

Answer:

Many are supergiants.

Explanation:

A star's size and core temperature determine its brightness. The brightest stars tend to be blue or blue white. Supergiants and red giants are in the region above the main sequence of stars, so that isn't true. Red are the dimmest. Yellow stars are in the middle of that spectrum. White Dwarfs are dimmer than the Sun, red giants and blue supergiants.

The sequence of events which produces another generation of organisms is called as the Life cycle.

What is Life cycle?

Life cycle is defined as the series of changes which members of a species undergo from the beginning of a given developmental stage to the beginning of the same developmental stage in a subsequent generation.

In many simple organisms including bacteria and various protists, the life cycle is completed within a single generation where an organism begins by fragmentation of an existing individual and the new organism grows to maturity which then splits into two new individuals, so the life cycle is complete.

Thus, the sequence of events which produces another generation of organisms is called as the Life cycle.

Examine the flow chart above depicting the job of a gene known as p53. It plays an important role during the G2 checkpoint of cell cycle regulation. In 4-6 sentences, explain why p53 is often called "The Guardian of the Genome". Is p53 an oncogene (a gene that stimulates the growth of cancer cells) or a tumor suppressor gene (a gene that turns off the growth of cancer cells)? Explain your reasoning.

Answers

The p53 protein is known as the guardian of the genome because this protein prevents errors during DNA replication. It is a tumor suppressor gene.

Tumor suppressor genes

Tumor suppressor genes are genes that play fundamental cellular roles and prevent cell uncontrolled growth.

A tumor suppressor gene can repair errors that occurred during DNA replication, slow down the cycle of cell division, trigger programmed cell death, etc.

The p53 acts to control cell division and cell death, thereby avoiding the emergence of cancer cells.

A. H+ ions will stop moving through the protein.
B. H+ ions will move in the other direction through the protein.
C. H+ ions will continue to move through the protein in the original direction but at a slower rate.
D. H+ ions will begin to move through the phospholipid portion of the membrane in the original direction.

Answers

H+ ions will stop moving through the protein is the effect of not having ATP

available to supply energy to this process.

ATP is the form of energy used by cells and it ensures that cells perform their

daily activities optimally. ATP is needed in a lot of metabolic reactions and

transportation of materials within cells.

When there is a lack of ATP, it means there is no energy required to

transport or move substances within a cell. This means that the H+ ions will

stop moving through the protein and is the most appropriate choice.

What is Transpiration ???!​

Answers

[tex]\huge \bf༆ Answer ༄[/tex]

Transpiration is the the phenomenon which generally occurs in plant, In which the plant looses water in the form of water vapour through stomata.

Two main functions of transpiration ~

It causes transpirational pull that helps in transportation of water from roots to upper portions of the plant

It helps to release excess water
Answer -:

Plant absorb a large quantity of water from the soil by roots . this water reaches to different part of the plant by ascent of sap . the total quantity of water absorbed by plant is more than their requirement. only a fraction of this water from a vapour throw the aerial parts like (stem , leaves , buds , and , flower) of plant which constitute about 95% of total absorbed water . this process is called transpiration .

Transpiration is vital process.This process mainly occur by stomata.Water evaporates in the form of vapour from aerial parts of plant.The loss of water per unit area is more It is regulated process

Types of Transpiration -:

1 Stomatal Transpiration ;

it take place through stomata present on leaves it is also called foliar Transpiration. it constitutes about 80-95% at total Transpiration.

2 Cuticular Transpiration;

it take place by cuticle present on the epidermis of plant it is constituted about 5-10% of total transpiration it rate is high in tropical climate and low desert climate.

3 Lenticular Transpiration

it take place through lenticles found in Woody stem and in some fruits it constitute 0.1-1% only of total transpiration.

4. How would having a high blood viscosity affect your ability to climb stairs? Explain your answer interms of homeostasis of oxygen/carbon dioxide levels

Answers

Having a high blood viscosity will slow down ability to climb stairs. This is

because high blood viscosity is associated with high blood pressure.

The binding of oxygen to the blood is reduced in a blood with high viscosity

as there is difficulty in the transport of blood for oxygenation due to its

higher density. This allows fro accumulation of carbon dioxide in the blood

which is harmful to body cells.

High blood viscosity will therefore reduce one's ability to climb stairs and

perform other activities.

The author makes the point that drivers must think of their needs when choosing between an electric car and a hybrid car. Select three sentences that the author includes in the article to support this point.Hybrid or Electric?These days, many people want to "go green." They know that burning gasoline causes pollution. So, people are thinking about buying an electric or hybrid car.Here is how electric cars work. Electric cars have large, powerful batteries. They send electricity to an electric motor. The motor turns the wheels. The batteries must be plugged in when they run low on energy.There are two types of hybrid cars. Both use gasoline and electricity in order to work. One type relies mostly on electric power. This car must be plugged in to receive a full recharge.The second type of hybrid car gets its power from a small gasoline engine. An electric motor serves as a backup. The electric motor also helps the car build up speed. This car recharges itself while it is running. When the driver brakes, that energy is stored in the battery.Today, gas prices continue to rise. Also, more people are worried about pollution. Thats why more "green" car models are being sold every year.Advantages of an Electric CarAn electric car costs little to recharge. It produces almost no pollution. This type of car cannot travel very far without needing to be charged.Electric cars can be recharged using any electrical outlet. Drivers can run an extension cord from their house to their car! However, charging a car this way can take a long time. Some cities have built charging stations. Recharging is much faster at one of these stations.Electric cars run very quietly. They also cost less to maintain because they have fewer parts. That makes the car more dependable. However, batteries have to be replaced every 1015 years. These batteries are very expensive. Some cost as much as $10,000!Advantages of Hybrid CarsHybrid cars can refuel at any gas station. If the batteries cannot be recharged, hybrids can run on gas for as long as necessary. However, their gas-powered engines require upkeep. Also, the batteries wear out in time.Electric and hybrid cars have one similarity. Right now, both cost more than gas-powered cars. However, that cost should come down eventually.Drivers must consider which type of car would be better for them. If drivers need a car for short trips, an electric car is perfect. If drivers travel far from home and cant charge a car, a hybrid would be the right choice. How were the perspectives of the Native Americans and the European explorers different?
