True
False
i believe the answer is true ^^
Answer: true?
Explanation:
In the daytime, sunlight shines into the greenhouse and warms the plants and air inside. At nighttime, it's colder outside, but the greenhouse stays pretty warm inside. That's because the glass walls of the greenhouse trap the Sun's heat. The greenhouse effect works much the same way on Earth.

The following flow diagram shows the various steps of elimination of waste through urine. There is an error in one of the steps. (5 points)
A flow diagram is shown with three rectangular boxes. Each box from top to bottom is labeled Step 1, Step 2, Step 3. The text written inside the top rectangular box reads, Urine flows from the ureters to the kidneys. The text written inside the middle rectangular box reads, The Ureters carry urine to the urinary bladder. The text written inside the bottommost rectangular box reads, Urine leaves the body through urethra. The title of the flow diagram is Elimination of Waste.
What is the error in the diagram?
Step 1 should be urine flows from the kidneys to the ureters.
Step 2 should be the kidneys carry urine to the bladder.
Step 2 should be the ureters carry urine to the urethra.
Step 3 should be urine leaves the body through kidneys.

Explanation:
Bats and birds eating insects at different times of day is an example of (1 point)
O survival of the fittest.
O resource partitioning.
O competitive exclusion.
O natural selection.
Bats and birds eating insects at different times of day is an example of Resource Partitioning. So, the correct option is B.
What is Resource Partitioning?
Resource partitioning or niche differentiation is a process of natural selection that will force competitors to use resources differently in such a way as to avoid competition between species. Resource partitioning causes the co-existence of species.
If bats and birds eat insects at different times of the day, there is no survival of the fittest. Competitive exclusion states that no two species can co-exist in the same niche for a long time.
Therefore, bats and birds eating insects at different times of day is an example of Resource Partitioning.

What are the characteristics of kingdoms archaebacteria?
Answer:
Archaebacteria are obligate or facultative anaerobes, i.e., they flourish in the absence of oxygen and that is why only they can undergo methanogenesis.
The cell membranes of the Archaebacteria are composed of lipids.
The rigid cell wall provides shape and support to the Archaebacteria. It also protects the cell from bursting under hypotonic conditions.
The cell wall is composed of Pseudomurein, which prevents archaebacteria from the effects of Lysozyme. Lysozyme is an enzyme released by the immune system of the host, which dissolves the cell wall of pathogenic bacteria.
These do not possess membrane-bound organelles such as nuclei, endoplasmic reticulum, mitochondria, lysosomes or chloroplast. Its thick cytoplasm contains all the compounds required for nutrition and metabolism.
They can live in a variety of environments and are hence called extremophiles. They can survive in acidic and alkaline aquatic regions, and also in temperature above boiling point.
They can withstand a very high pressure of more than 200 atmospheres.
Archaebacteria are indifferent towards major antibiotics because they contain plasmids which have antibiotic resistance enzymes.
The mode of reproduction is asexual, known as binary fission.
They perform unique gene transcription.
The differences in their ribosomal RNA suggest that they diverged from both prokaryotes and eukaryotes.
Answer: Archaebacteria are obligate or facultative anaerobes, i.e., they flourish in the absence of oxygen and that is why only they can undergo methanogenesis.
The cell membranes of the Archaebacteria are composed of lipids.
The rigid cell wall provides shape and support to the Archaebacteria.
