3. When the Moon appears to be growing it is called...
A-Gibbous
B-Waning
C-Waxing
Answer:
waxing
Explanation:
When the Moon appears smaller than a quarter, we call it a crescent. When the Moon appears larger than a quarter, we call it gibbous. When the moon is getting bigger (phases New to Full) it is waxing. When it is getting smaller (phases Full to New) it is waning.

how does a bryophyte excrete?
Answer:
They do not excrete
Explanation:
Bryophytes have neither pollen nor flowers and rely on water to carry the male sperm to the female eggs. The spore capsules are produced after a male gamete (the sperm) has fertilized a female gamete (the egg). Hence the spores are part of the sexual reproductive cycle.
Answer:
Bryophytes excrete with the help of erect stem with spirally arranged leaf like structures and with rhizoids (hair like structures that function as roots) at the base.

how does reducing gene flow cause speciation
Answer:
reduction of gene flow can occur due to geographical isolation too
or it can be dur to sympatric or allopatric speciation an occur.
where due to this the species are being behaviouraly isolated, and mad too reject mating due to certain reasons. Moreover mutations too can take palace causing for a genetic drift. Where the isolated species may undergo selection pressure too. So as an overall view the gene flow eventually decreases since the species diversity along with the genetic diversity decreases causing fare the reduction of the gene pool.
After many generations a new species will be formed. Resulting for speciation.
(refer to the AL biology text book under biodiversity related topics, it will be easy)
Organisms are interdependent by all taking part in a food chain. Organisms rely on each other to sustain the ecological environment, something that humans have been lacking in. So, in general, organisms are interdependent because they have no choice.
Explanation:
Plants and animals need to coexist in order to thrive. Plants need animals just as much as animals need plants. A simple example of this would be trees. Trees provide many things to many different organisms but I will use shelter as an example. Trees provide shelter to many animals such as birds, so in essence they protect birds. Birds eat plants and in turn spread the seeds which grow. Insects, like bees, collect pollen from the flowers, etc. It is all part of a complex system in which species all depend on one another for some specific reason. So, interdependence is when plants and animals depend on each other for survival.
In general, the interdependency of organisms extends ecologically to their environment. Organisms rely on each other to sustain the ecological environment, something that humans have been lacking in. So, in general, organisms are interdependent because they have no choice.

Explanation:
What can be a recessive or dominat??
Answer: There are many examples of recessive traits in non-human animals as well. In dogs, traits like yellow fur, white spots, and smooth hair are recessive. In cats, white fur, brown (as opposed to black) fur, and long hair are recessive traits. In sheep, black wool and blue eyes are recessive.
Also Dominant refers to the relationship between two versions of a gene. Individuals receive two versions of each gene, known as alleles, from each parent. If the alleles of a gene are different, one allele will be expressed; it is the dominant gene. The effect of the other allele, called recessive, is masked.

2 paragraphs about Ecosystems: What is an ecosystem?
Answer:
An ecosystem is a geographic area where plants, animals, and other organisms, as well as weather and landscapes, work together to form a bubble of life.
An ecosystem is a community of living organisms in conjunction with the nonliving components of their environment, interacting as a system. These biotic and abiotic components are linked together through nutrient cycles and energy flows.
SOMEONE PLEASE HELP Which of the following examples is MOST likely to result in the formation of a new species? Select one:
A
A farmer applies a new fertilizer to her crops in order to encourage a much greater yield of corn.
B
An invasive species is introduced into the sea when an oil tanker releases the water it uses to float near a coral reef.
C
Many trees are knocked down when a new road is paved through a forest where many animal species live.
D
A fish population is divided when a long drought causes a lake to separate into two smaller bodies of water,
Answer: D
Explanation: The important thing to notice in this question is that it's asking for the FORMATION of a NEW species. That detail automatically removes B as the answer, because, while an invasive species could lead to a new species, it isn't likely, and there's the fact that B is talking about the INTRODUCTION of a species that already exists.
A could be correct, but fertilizer isn't likely to lead to a new species, as well as C, which would lead to a LOSS in species and biodiversity.
D is correct because it is an example of Allopatric Speciation, which is when one species converges into 2 species because of a physical barrier.

How does geography influence climate?
Answer:
Geography affects the weather in many ways. ... Topographical features like mountains affect the weather mostly in the way that they direct air currents. For example, air is forced to rise over mountains. Moist air will cool as it rises, and then the clouds release the water, causing precipitation like rain or snow.
