With respect to one another, galaxies have been found to be
1. moving closer together
2.moving farther apart
3.moving in random directions


The answer is moving farther apart

With respect to one another, galaxies have been found to be moving farther apart from each other. The correct option is 2.

What are galaxies?

Galaxies are large areas that contain stars, dark matter, dust, interstellar gases, etc. It is a gravity-bound system that contains everything in its own place.

There are many galaxies, some are still undiscovered. Our galaxy in which the earth is present is called the Milky Way. It is called the Milky Way because due to many stars it looks like a shiny white path.

Now, the Big Bang Theory says that the universe is made up of expanding of a single point. And the universe is still expanding, so the galaxies' and other matters still going farther away.

Thus, the correct option is 2. Moving farther apart.

does not
Heredity always involves changes in inherited characteristics, whereas reproduction
does not



Reproduction is the process of producing offspring, whereas heredity is the process

of passing on traits.


PLEASE MARK BRAINLIEST, if you think this is correct and best! Thanks!

Reproduction generally means making copy of something, like giving birth/breeding, duplicating.

Heredity is inheritance of traits/ passing on traits from parents t thsir child/children through genes. It makes children have same traits as their parents and looks so what same like their parents!

They definitely aren’t same!

Reproduction is the process of producing offspring, whereas heredity is the process of passing on traits.

What do you mean by heredity?

Heredity, also called inheritance or biological inheritance, is the passing on of traits from parents to their offspring; either through asexual reproduction or sexual reproduction, the offspring cells or organisms acquire the genetic information.

Heredity explains why offspring resemble, but are not identical to, their parents and is a unifying biological principle. Heredity refers to specific mechanisms by which characteristics or traits are passed from one generation to the next via genes.

Heredity can be defined as the transfer of genetic characters from parents to offsprings by the process of fertilization, where the nuclei of male and female gamete fuses with each other and forms the genetic material of the zygote.

(A) rate=
(B) rate=
(C) rate=
(D) rate



(A) rate=





The rate of chemical is a measure of the speed of a chemical reaction.

The measurement of the reaction rate is based on the disappearance of a reactant or appearance of a product with increasing reaction time.

Reaction rate is usually expressed in terms of a change in concentration of the chosen reactant or product per unit of time.

During a reaction, the concentration of the reactant decreases exponentially with time while that of a product increases exponentially with time.

Reaction rate  = [tex]\frac{change in concentration of a reactant/product}{Time taken}[/tex]

If the beetles disappeared from this community, which changes would be
likely to occur? Select the three correct answers.

A. An increase in the number of strangler figs

B. A decrease in the population of sloths

C. A decrease in the number of boa constrictors

D. An increase in the population of fruit bats

E. A decrease in the population of poison dart frogs



A, C, E


If the beetles disappeared from this community, changes likely to occur include

an increase in the number of strangler figs, an increase in the population of fruit bats and decrease in the population of poison dart frogs

The beetles are insects which eat up strangler figs and a decrease mean an increase in its number.

The population of fruit bats will increase as they will have more strangler figs available for food.

Poison dart frogs will decrease because they feed primarily on beetles in the ecosystem.

Does Soil Affect Flower Color?

Garden Care


Mary Simpson

This flower must have grown in neutral soil, with little aluminum.

In some varieties of bigleaf hydrangeas (Hydrangea macrophylla), soil pH determines whether the plant will produce blue or pink flowers. Blooms appear bluest when grown in acidic soil with a pH in the 5.0 to 5.5 range. The same cultivar may sport pink blossoms in soil with a more neutral pH, such as 6.5 to 7.0. Florists control flower color by potting soil mixture

23. Lipids


Carbohydrates are organic molecules composed of carbon, hydrogen and oxygen. Carbohydrates can be classified into three types: monosaccharides (e.g. glucose), disaccharides (e.g., lactose), and polysaccharides (e.g., starch). Cellulose is a carbohydrate where many glucose rings chain together, while chitin is a polysaccharide consisting of chains of modified glucose molecules.

Lipids represent a diverse group of organic molecules that include, among others, fats, waxes, oils, hormones, etc. Lipids play a role by insulating (and protecting) the body. For example, there is a layer of fats beneath the skin which enables to maintain body temperature relatively constant. In animals, lipids constitute about 50% of the mass of cell membranes. These membrane lipids are mainly phospholipids, glycolipids and cholesterol. There are hormones that derive from lipids such as steroid hormones, which derive from cholesterol. Some examples of steroid hormones are testosterone, estrogen and cortisol.

What groups of organisms are most in danger of extinction?

A. Those with small population
B. Those that migrate or need special habitats
C. Those with large populations that breed quickly
D. Both a and b



D.Both a and B

As organisms with small population and those who migrate and need special habitat are most in danger of extinction.

The group of organisms that are in danger of extinction is those that have small populations and those that migrate or need special habits. So the correct option is D.

What is the extinction of species?

In biology, extinction refers to the extinction or death of a species. Extinction happens when a species' numbers are reduced due to evolutionary changes in its members, such as genetic inbreeding, poor reproduction, and population decline, or due to environmental factors like habitat fragmentation, climate change, natural disasters, and overexploitation of the species for human use.

The majority of species that have ever existed on Earth have gone extinct, but the fossil record indicates five very significant extinctions, known as mass extinction events, each of which resulted in the extinction of enormous numbers of species. The bulk of extinctions, which happen continuously and are described as background extinctions, are separated from these glaring decreases in the variety by the term "mass extinction."

Therefore, the correct option is D.

What describes G and why they face the watery inside and outside of the cell



Because they are hydrophilic


The cell membrane is made up of a phospholipid bilayer. The phospholipid bilayer is made up of an arrangement of phosphate heads, which are (attracted to water) hydrophilic, and fatty acid tails, which are hydrophobic. (repelled by water).

Because they are attracted to water, the phosphate heads face the outside of the cell, where the water is

Which two of the following correctly describe what a gene is?

A packet of genetic information that can be passed down from one generation to the next
A DNA molecule
The entire collection of genetic information in a given species
A section of DNA that provides instructions for building a specific protein

A section of DNA that provides instructions for building a specific protein and A packet of genetic information that can be passed down from one generation to the next


A DNA molecule is not a gene, it is a nucleotide. The entire collection of genetic information in a given species results isn't a gene although many genes comprise what is the genome.  Given that those two answers are not what genes are, the other two options are correct.

Which one can be broken down further and element or a compound?



Elements are the simplest form of matter; cannot be broken down further by either physical or chemical means. Compounds are made up of two or more elements combined in definite quantities and in definite proportions by chemical bonds.





Genetic variation is the difference in DNA among individuals or the differences between populations. There are multiple sources of genetic variation, including mutation and genetic recombination.



Genetic variation refers to diversity in gene frequencies. Genetic variation can refer to differences between individuals or to differences between populations. Mutation is the ultimate source of genetic variation, but mechanisms such as sexual reproduction and genetic drift contribute to it as well.

What is the effect of temperature on ATP,NADPH, and sugars? Will the increase, decrease, or stay the same?



1. ATP will increase

2. NADPH will increase

3. Sugar will decrease


Had the same problem

The effect of temperature on these molecules are ;

ATP will increase NADPH will also increase  while Sugars will decrease

ATP (  Adenosine triphosphate ) is the molecule in cells which stores energy in cells while transferring the energy needed within cells as well. When the temperature of a cell is raised above the required temperature this molecule will also increase in response.

NADPH is an electron donor which is found in organisms, it also provides the reducing power for certain reactions in the organism ( anabolic ) and the gathering of NADPH oxidase. increases as the temperature of the organism increases.

Hence we can conclude that as temperature increases , ATP will increase , NADPH will increase while Sugars will decrease.

what makes angiosperm more advance than gymnosperm​


Answer& Explanation:

Angiosperm is more advanced due to the mechanism of protection it has since developed as opposed to its predecessor, gymnosperm. Angiosperms could be deemed the inventors of animal-mediated pollination or dispersal, whereas gymnosperms mostly depend on wind-mediated pollination (which is far more of a gamble than animal mediated).

1) Angiosperms seeds are enclosed in fruits, which increases the chances of dispersal by either wind, water, or animals. Animals can eat the fruit and disperse the seeds via feces or by brushing the fruit off of their fur coats new areas of the terrain.

2)The development of flowers. Flowers are especially important because depending on the flower it can attract a set species of animals in order for pollination to occur. That species of animal could only focus on those few flowers and would allow the female part of the flower to receive pollen (produced by the male part of the flower) from all over the place. This theory is also applicable to animal mediated fruit dispersal.

Flowering plants mature more quickly than gymnosperms, and produce greater numbers of seeds. The woody tissues of angiosperms are also more complex and specialized. Their seeds are enclosed in a fruit for easy dispersal by wind, water, or animals.
