Contains the instructions needed for an organism to develop, survive and reproduce. To carry out these functions, DNA sequences must be converted into messages that can be used to produce proteins, which are the complex molecules that do most of the work in our bodies.

If there are two weights on the scale, one 1.5m from the fulcrum weighing 1.7 kg, and the second 1.2m from the fulcrum, what mus
kykrilka [37]

The fulcrum is the point in any mechanical device where the moment due to weights is zero.

(Weight 1 x distance 1) - (weight 2 x distance 2) = 0

(1.7 Kg x 1.5 m ) - (weight 2 x 1.2 m) = 0

weight 2 = (1.7 Kg x 1.5 m ) / 1.2 m

= 2.1 Kg

natali 33 [55]

The explanations of natural phenomena, and additional hypothesis most often come about as a result of a scientific theory.

Explanation:

Scientific theory is a general explanation of natural phenomena developed through extensive and reproducible observations, more general and reliable than a hypothesis.

Then Every scientific theory starts as a hypothesis. A scientific hypothesis is a solution for an unexplained occurrence that does not fit into a currently accepted scientific theory. It must be based on careful rational examination of the facts.

which structure in leaves allows the gaseous reactants and products of photosynthesis to move in and out a b c d
Zepler [3.9K]

Answer:

Stomata

Explanation:

Photosynthesis is a unique phenomenon which occurs in the Chloroplast of plant cells. It is the way they synthesize their food in form of glucose. However, like every metabolic reaction, photosynthesis requires certain reactants and products.

Photosynthesis combines carbondioxide (CO2) gas and water (H2O) in the presence of sunlight to produce Glucose (C6H12O6) and oxygen gas (O2). The gaseous components of this metabolic activity enters (C02) and leaves (O2) the plant via a structure in the leaves called STOMATA.

STOMATA is a pore found in the epidermis layer of plant leaves that aids in the exchange of gases i.e. carbondioxide in, oxygen out during Photosynthesis.

uhm i have 5 questions due in an hour so please help. It's 45 points and they're all abt biology btw~
Mariulka [41]

Answer:

the point of science is to disprove hypothesis so having a hypothesis that doesn't allow that to happen is not good science

2. they don't fit in our mouths so are a trait from when we had larger jaws

3. bones of your lower jaw, middle ear and voice box (they aren't actually gills fyi, they just look like them)

4. likely yes as their bones were hollow but likely only able to fly short distances, the thought was that they couldn't do their size and weight but with hollow bones they were able to like a quail would

5. no because they could be sister taxa, you would have a hard time proving exactly that this new fossil is the common ancestor that birds came from to replace the old hypothesis (guess) of which one did.
