How does the movement of particles of matter change when temperature increases?
Decreases
Increases
Increases then decreases
Does not change

Answers

Answer:

Increases

Explanation:

The movement of particles of the matter increases with the increase in temperature.

The particles gain kinetic energy with increasing temperature and move in faster rate.

For example: When we blow a balloon with our mouth, we increases the temperature inside the balloon, the particles in the balloon gain kinetic energy that leads to the faster movement of gas particles in the balloon and they collide with each other and surface of balloon, after a peak the balloon get burst because of high kinetic energy and high collision.

Hence, the correct answer is "increases".

29. Brain has one son, two grandchildren, and three great-grandchildren. This is example of
O exponential growth.
Odynamic growth.
O linear growth.
Obinary growth.

Answers

This is an example of exponential growth.

Exponential growth refers to a pattern of growth where the quantity or size of something increases at an accelerating rate over time.

In the given scenario, Brain has one son, two grandchildren, and three great-grandchildren.

Each generation is producing more offspring, resulting in a rapidly increasing number of descendants.

The progression from one generation to the next demonstrates exponential growth because each subsequent generation adds more individuals than the previous one.

As the generations continue, the number of descendants grows exponentially larger.

Exponential growth can be observed in various natural and human-made systems, such as population growth, compound interest, and the spread of infectious diseases.

In this case, the number of descendants in Brain's family tree follows an exponential pattern, as each new generation multiplies the number of offspring, leading to a significant growth rate.

Therefore, the example given aligns with the concept of exponential growth.

Assume that a pinhead is 1mm how many spherical bacteria lined up side by side would fit across the pinhead

Answers

The no. of bacteria lined up side by side would fit across the pinhead is 1000.

We know that the average size of cocci bacteria is 1 micrometer and 1mm = 1,000 micrometer.

Thus, on a 1mm size pinhead a total of 1000 cocci bacteria should be fit.

Cocci bacteria are spherical because their bodies are round. We can determine whether they are gram-positive or gram-negative by looking at the makeup of their cell walls. There are numerous genera in the Coccus class.

The Greek term "coccus" denotes a spherical body. Staphylococcus, a species that causes phenomena in humans, is the greatest example of a cocci. They are really tiny in size. All cocci bacteria differ from one another in terms of their physiological characteristics, but their bodies are always round. This means that while their size and colour may vary, the shape of their bodies is always cocci or round.

Answers

Answer:

He should request type O on his dating survey.

Opine's blood type must be AO to have a higher probability of producing O offsprings.

Explanation:

O blood type is recessive so, when it is paired with another blood type like B or A, these would be dominant, giving B and A blood, respectively.

O blood type results are possible thanks to OO genotypes.

If the man's blood type is A, to have a higher chance of producing OO offsprings, his blood should be AO. The other possibility is that he has AA blood, which will result in a low probability of OO offsprings.

As regards the mother, her blood type should be OO.

We can see this more clearly in Punnet Square.

║ A ║O

O║AO║OO

There is a 50% of probability of having O offsprings with AO and OO.

║ A ║A

Which option lists the level of the biosphere that are broader than community?

-biome, population
-ecosystem, population
-biome, ecosystem
-ecosystem, individual

Answers

The option that lists the levels of the biosphere that are broader than the community is "biome, ecosystem."

In the hierarchy of the ecological organization, the community refers to the assemblage of different species that interact and coexist within a specific area. It represents the interactions among populations within a defined habitat. The community level focuses on the relationships between different species and their interactions.

Moving up the hierarchy, the next broader level is the ecosystem, which includes not only the community but also the physical environment in which the organisms live.

An ecosystem encompasses the biotic (living) and abiotic (non-living) components and their interactions within a particular area. It includes the community of organisms along with the physical factors such as climate, soil, water, and nutrient availability.

Above the ecosystem level, the next broader level is the biome, which refers to large-scale geographical areas characterized by distinct climate patterns, vegetation types, and ecological characteristics.

Biomes are broad categories that encompass multiple ecosystems sharing similar environmental conditions and supporting similar types of communities.

Therefore, the correct option is "biome, ecosystem," as it accurately represents the levels of the biosphere broader than the community.

Answers

The two pieces of evidence that support the theory of the expanding universe are the red shift of light from distant stars and the existence of cosmic background radiation.

The correct answer is option B.

1. Red shift of light from distant stars: The observation of redshift in the light coming from distant galaxies provides evidence for the expansion of the universe. Redshift occurs when the light waves from an object moving away from an observer are stretched, causing a shift towards longer wavelengths. This phenomenon is consistent with the Doppler effect, where the wavelength of light appears to stretch as the source moves away. The redshift of light from distant stars indicates that galaxies are moving away from us and from each other, supporting the idea that the universe is expanding.

2. Existence of cosmic background radiation: The discovery of cosmic background radiation further supports the theory of the expanding universe. Cosmic background radiation is a faint, uniform microwave radiation that permeates the entire universe. It is believed to be residual radiation from the Big Bang, the initial event that is thought to have initiated the expansion of the universe. The presence of cosmic background radiation provides strong evidence for the hot, dense early stages of the universe and its subsequent expansion.

Answers

Answer:

"Proton decreases" would be the right approach.

Explanation:

The Kreb cycle or system plays a key role throughout a matrix of mitochondria. 3 NADH, 2 FADH2 as well as 1 ATP are synthesized. Whenever the Kreb process has been halted, the acetyl CoA throughout the Kreb cycle has not been used. Pyruvate doesn't at all, disintegrate via acetyl CoA. Therefore in cells, pyruvate accumulates. Unless the Kreb loop is halted, therefore the concentration of NADH and FADH2 declines.

Thus, they aren't used for the transportation chain of electrons. This is also why protons have not been discovered to be injected towards intermembrane space.
