What is the most important part in the respiratory system?
The lungs.
The lungs are paired, cone-shaped organs which take up most of the space in our chests, along with the heart. Their role is to take oxygen into the body, which we need for our cells to live and function properly, and to help us get rid of carbon dioxide, which is a waste product.

An animal has 2 genes: 1 for tail length (T) and 1 for head shape (H). Its genotype is TtHh. What are all of the possible gametes that this organism can make?
Answer:
TH, Th, tH, th
Explanation:
This question involves two genes; one coding for tail length and the other for head shape. According to this question, an organism has the genotype: TtHh.
In accordance to the law of independent assortment, which states that alleles of one gene will segregate independently of one another. The meiotic division of the organism, will occur in such a way that only one allele of each gene is present in any GAMETE.
The possible gametes for the genotype: TtHh are: TH, Th, tH, th

Which of the following is NOT true about Earth’s systems? A.Together, the the geosphere, hydrosphere, atmosphere, and biosphere work to support life on planet Earth. B. Our atmosphere is the place that holds our oxygen. C. There are many systems, or, parts, that work independently. D. There are many , systems, or parts, of the Earth that work together.
Answer:
d
Explanation:
because each part and system as individual tasks or ways to help the earth
The statement that is not true is that there are many systems, or, parts, that work independently. The correct option is C.
What is Earth's system?The application of systems science to the Earth is known as earth system science. It focuses on interactions and 'feedbacks' in particular.
The five Earth systems interact to create the environments we are familiar with.
Everything in the Earth's system can be classified as either land, water, living things, or air. These four components of the system are referred to as "spheres."
They are the "lithosphere" (land), the "hydrosphere" (water), the "biosphere" (living things), and the "atmosphere" (air).
The geosphere is split up into four subsystems: the lithosphere, hydrosphere, cryosphere, and atmosphere.
Because these subsystems interact with one another and with the biosphere, they work together to influence the climate, trigger geological processes, and influence life on Earth.
Thus, the correct option is C.

A gardener wanted to know if E-Z fertiliser would be good for his vegetables. He fertilised all his bean plants with E-Z fertiliser but didn’t put any fertiliser on his pepper plants. His beans didn’t do well at all, but he got a good crop of peppers. He concluded that E-Z fertiliser was no good. What are the errors in this experiment? Tick all that apply
A) Not enough subjects
B) Subjects were not similar
C) Conditions were not kept the same
D) The experiment was not reproduced
Answer:
B) Subjects were not similar
The errors in this experiment are: subjects were not similar and conditions were not kept the same. Hence the correct options are B and C.
Subjects were not similar: The gardener used two different types of plants, beans, and peppers, to test the effectiveness of E-Z fertiliser. Beans and peppers have different growth requirements, nutritional needs, and environmental preferences. By using different types of plants as subjects, the experiment introduces variability and makes it difficult to attribute the outcome solely to the fertiliser.
Conditions were not kept the same: The gardener applied E-Z fertiliser to the bean plants but did not provide any fertiliser to the pepper plants. This difference in treatment introduces a significant confounding factor, making it impossible to isolate the effect of the fertiliser on the bean plants' poor performance.
Hence the correct options are B and C.

A change in an organism’s surroundings that causes the organism to react.
Answer:
stimulus
Explanation:
When a filament of algae is illuminated with light that is passed through a prism, different segments of algae are exposed to different wavelengths of light. When aerobic bacteria are present, they congregate in highest concentrations in the areas illuminated by the red and blue light. These data suggest a relationship between which of the following variables?
a) Wavelength of light and rate of aerobic respiration
b) Wavelength of light and amt of heat released
c) Wavelength of light and the rate of photosynthesis
d) Carbon dioxide concentration and the rate of photosynthesis
Answer:
The correct answer is C) wavelength of light and rate of photosynthesis.
Explanation:
The given question is a famous experiment conducted by T W Engelmann which is called the action spectrum experiment. In this experiment when light passes through a prism it splits into its constituent colors splits into violet, indigo, blue, green, yellow, orange and red.
Aerobic bacteria require oxygen for their survival. The green algae produce oxygen during photosynthesis. Engelmann released aerobic bacteria to it. it is found that the bacteria accumulated at the blue and red light because photosynthesis and oxygen release were higher there. So, it establishes the relationship between the wavelength of light and photosynthesis.

How many paths through which charge can flow would be shown in a circuit diagram of a parallel circuit? more information is needed. none two or more one
Answer: More than 1
Explanation:
A parallel circuit is defined by having more than one path through which current can flow. This is in contrast to a Series circuit where the current flows through just one path.
Even though there are multiple paths for the current to flow through, the current flowing through all the paths must add up to the total current that is being supplied from the source.
