The Moon passes between the Sun and Earth.
The Sun, the Moon, and the Earth form a right angle.
Earth and the Moon are on opposite sides of the Sun.
Earth and the Moon are at their farthest distance from the Sun.
Answer:
a)The Moon passes between the Sun and Earth.
Explanation:
Sometimes when the moon orbits Earth, it moves between the sun and Earth. When this happens, the moon blocks the light of the sun from reaching Earth. This causes an eclipse of the sun.

Why would we not have animals without plants?
try to create an original enough answer! ^^ Thank you!
Answer: Humans and animals use the oxygen (O2) in the air for their energy process and produce CO2 as waste. A plant does the exact opposite. ... If there were no plants on the planet we wouldn't be able to breathe. Humans in particular, however, also produce other waste
Explanation:
What are chromosomes? When do chromosomes form?
Answer:
Chromosomes are coiled structures made of DNA and proteins. They contain genes, which basically code for proteins. Chromosomes form after DNA replicates. In other words, chromosomes form as DNA becomes foiled during the process of prophase I, thus creating chromosomes.

Answer:
PROTIENS............... i think.
Explanation:
Scientists have observed that new crust, such as mid-ocean ridges, is formed where two plates are moving away from each other. Based on this observation and the data on the maps, where do you suspect that old crust is destroyed and recycled? Provide three specific locations on the map where you think this process is occurring
Answer:
Old crust is destroyed at boundaries where two plates are moving toward each other, or converging. Specific examples include the Australian and Pacific plates, the Caribbean and Cocos plates, and the southwest corner of the North American plate and the Pacific plate.

where do all of the cells in the human body come from
Answer:
Every cell in the body originates from a single fertilized egg called a zygote. The zygote divides repeatedly to produce an embryo. These embryonic cells continue to divide, differentiating into all the cell types present in the body of all humans (and other mammals), from a new-born baby to an elderly adult
Answer:
The zygote
Explanation:
I'm not exactly sure what you're talking about, but this is what I found: "Every cell in the body originates from a single fertilized egg called a zygote. The zygote divides repeatedly to produce an embryo. These embryonic cells continue to divide, differentiating into all the cell types present in the body of all humans (and other mammals), from a new-born baby to an elderly adult."
What is the full function of the inner ear.
Answer:
The inner ear is primarily responsible for balance, equilibrium and orientation in three-dimensional space. The inner ear can detect both static and dynamic equilibrium. Three semicircular ducts and two chambers, which contain the saccule and utricle, enable the body to detect any deviation from equilibrium. The inner ear (also called the labyrinth) contains 2 main structures — the cochlea, which is involved in hearing, and the vestibular system (consisting of the 3 semicircular canals, saccule and utricle), which is responsible for maintaining balance.

What does it mean to be a "pioneer"? Using your explanation, what do you think it means if something is a "pioneer species"?
Answer:
to be one of the first people to do something:
a person who is among the first to study or develop something
Explanation:
Pioneer species are hardy species which are the first to colonize barren environments or previously biodiverse steady-state ecosystems that have been disrupted, such as by fire.[1] Some lichens grow on rocks without soil, so may be among the first of life forms, and break down the rocks into soil for plants
What is the meaning of inland?

a given gene sequence contains 49 adenine base pairs. how many thymine bases will be included in the RNA strand?
a. 49
b. 98
c. 24
d. 0
Answer:
b
Explanation:
If there are 49 pairs you would have to multiply it by 2 to get your original number.
The fundamental and functional elements of genetics are called genes. it is composed of thread-like DNA structures found in the coiled form. Genes direct the formation of the proteins required for cellular activities.
0 thymine bases will be included in the RNA strand.
How to know the number of nucleotide bases?In a DNA or RNA molecule, the number of nucleotide bases is given by Chargaff's rule. Nucleotide bases are the structures of the purine and the pyrimidine rings.According to the base-pairing rule, an adenine base will always pair with thymine in DNA and uracil in the RNA molecule similarly the guanine will bond with the cytosine in the DNA or RNA molecules and vice versa.As the RNA molecule does not have thymine but codes for uracil will not base pair with the complementary adenine base.Therefore, option d. 0 thymine will be included in the RNA strand.

Field mustard is an annual plant that grows wild in many regions of the world. It has small yellow flowers and is pollinated by insects. Field mustard has to flower and produce seeds to give rise to the next generation. Southern California experienced a severe drought between 2000 and 2004. Plants that flowered earlier reproduced. Those that flowered later died without producing seeds. This led to more early-flowering field mustard plants. This change in population characteristics took only a few generations.
How do you think scientists discovered that the flowering time of the field mustard had changed?
Answer:
Due to early flowering in the mustard plant.
Explanation:
The scientists discovered that the flowering time of the field mustard had changed by observing more mustard plants which produces earlier flowers. The behaviour of the mustard plant change due to the change that occur in the environmental conditions that leads to early flowering in mustard plant. If this early flowering occurs for more generation, then the mustard plant will adopt this type of behaviour in normal environmental conditions that experience by the mustard plant.

a. DNA is produced by protein which is produced in the cell
b. dna controls the production of protein in the cell
c. protein is composed of DNA which is produced in the cell
d. a cell is composed of DNA and protein
Answer:
Cells contain DNA that controls the production of proteins. (2) DNA is composed of proteins that carry coded information for how cells function. (3) Proteins are used to produce cells that link amino acids together into DNA. (4) Cells are linked together by proteins to make different kinds of DNA molecules.

whats stigma in a plant
[tex]\huge{ \underline{\boxed{\red{ \color{red}{\textsf {\textbf{An}{\color{blue}{\textbf {\textsf{sw}}{\color{green}{\textbf{\textsf{er}}}{\color{orange}{\textsf{\textbf{~:-}}}}}}}}}}}}}[/tex]
The stigma is the sticky knob at the top of the pistil. It is attached to the long, tubelike structure called the style. The style leads to the ovary that contains the female egg cells called ovules. The male parts are called stamens and usually surround the pistil.
In a flower, this landing zone and entrance is the stigma. It plays a pivotal role in reproduction. Most stigmas are adapted to trap pollen with hairs, flaps and other surfaces to increase their efficiency. Most stigmas are covered with a waxy, sticky substance.
Answer:
Stigma: The part of the pistil where pollen germinates.

What do you think will happen when you breed two green-and-pink spotted aliens?
Answer:
They will have a green-and-pink spotted alien most likely.
Explanation:
Since a dominant gene is the gene that we see represented in the physical appearance of an animal or human, we can only estimate that green-and-pink spots are the dominate gene because both aliens have them. Our best guess is that the two green-and-pink spotted aliens will breed a green-and-pink spotted baby alien. However, this is not 100% full proof.
Hope this helps!
Answer:
Born aliens may be with green spots, or with pink spots or with both colors of spots.
