investigation?
A. It is a question that can be answered by gathering data during an
experiment.
B. It is a question that can be answered by gathering other scientists'
opinions.
O C. It is a question about a phenomenon of which no measurements
can be taken
D. It is a question about the sequence of experimental steps.
SUBMIT
Answer:
A.
Explanation:
This is true because scientific investigation is that of experimenting and collecting data to create an analysis and conclusion. The only way to answer a question with scientific investigation is by gathering data during and experiment. A scientist's opinion is not data, but a thought that is not solid and can change. It is not always backed up by facts. Measurements must be taken when you answer a scientific question with data. This is why A is the correct answer. hope this helped

Coloration in mockingjays is determined by a single gene. The G allele leads to grey colored feathers and the g allele leads to all white feathers. If two heterozygotes are crossed, what would be the phenotypic ratio in the F1 progeny? What would be the genotypic ratio in the F1 progeny
Answer:
F1 genotype = 1: 2: 1
F1 phenotype = 3:1
Explanation:
given data
G = allete for grey colour feather
and
g = allele for white colour fether
and
Gg = genotype of heterozygotes
we do here cross of two heterozygotes that is
parantal generation Gg × Gg
⊥ ⊥
G g G g
gametes ⇒ F1 generation
F1 genotype = 1: 2: 1
F1 phenotype = 3:1

A food change is an ecosystem flows from green algae, to freshwater snails, to small fish, and finally to large fish. Which organism is the primary consumer?
Large Fish
Small Fish
Green Algae
Freshwater Snails
Answer:
The correct answer is - freshwater snails.
Explanation:
Producers are organisms that produce their own food and not depends on any other organism by the process of photosynthesis such as algae. Primary organisms on the other hand directly depend on the producers for their food and often gt killed by secondary consumers.
Freshwater snails are the perfect example of the primary consumer as they get their food and energy from algae and are the primary source of food and energy for small fishes.

Explanation:
Answer:
they tend to cause problems wherever they don't live. Or where they didn't originate.
Explanation:
If an exotic species is not in its natural habitat than it can cause and have many problems.
In most cases What happens to a liquid when it cools
Answer:
it evolve heat to surrounding
Answer:
Density Increases, its Mass Decreases, Its Volume Increases.
Explanation:
"Genetic power is far more potent than atomic power. And it will be in everyone's hands. It will be in kits for backyard gardeners. Experiments for schoolchildren. Cheap labs for terrorists and dictators. And that will force everyone to ask the same question—What should I do with my power?— which is the very question—science cannot answer."
Answer:
These facts are true and disturbing
Explanation:
Genetics is a discipline that has advanced incredibly in the last years. For example, by using the versatile CRISPR-Cas9 genome editing system, we are now able to insert literally any sequence into a given genome in vivo. The CRISPR-Cas9 is a technology that can be used in a regular molecular biology laboratory. It is expected this technique will enable in the near future to correct genetic disorders that have plagued mankind since times immemorial. However, genomic technologies like that could be used by malignant persons to hurt innocent people, thereby it is imperative that countries regulate their use.
What conditions are needed to form organic molecules from inorganic molecules? (A: Abundance of oxygen and the ozone layer) (B: Active volcanoes and very cold temperatures) ( C: Presence of inorganic molecules with lightning and intense radiation) (D: Low levels of ultraviolet radiation and a specific mixture of gases).
Answer:
c
Explanation:
the theory suggest that formation of organic molecules takes places by the help of inorganic material along with lightening and intense radiation
Lightning and strong radiation in the presence of inorganic compounds. Thus option C is incorrect.
What is abiogenesis?Abiogenesis is the process of forming organic molecules from inorganic ones.
This is thought to be how the first organic compounds were formed around 3.8 billion years ago on early Earth. The classic Miller–Urey experiment from 1952 aimed to recreate the early earth's conditions. They used electric parks to simulate lightning strikes in a glass with greenhouse gases such as methane, which are thought to have been key parts of the early Earth's atmosphere. This experiment resulted in the formation of primitive organic compounds.

Answer:
Nucleic acids.
Explanation:
Extremely helpful Bio mnemonics to remember are:
Carbohydrates & Lipids - CHO
Proteins - CHON
Nucleic acids - CHONP
Because of the "CHONP" mnemonic, I was immediately able to recognize the compound as a nucleic acid after seeing the "P", which represents phosphorous.
Carbohydrates, lipids, nor proteins will include "P"; only nucleic acids.
Gastrin secretion in response to elevated ph within the stomach is an example of:__________.
Answer:
It is an example of enzyme activation through the pH of the environment surrounding the enzyme.
This phenomenon is called proenzyme, proenzymes are inactive enzymes that, due to chemical changes in the environment that vary, are activated or not depending on these.
Explanation:
Proenzymes, generally the best known or named, are found in the digestive system, where the sequential digestion of food is essential, with an order, and the enzymes must be controlled or activated at certain moments of digestion.
Proenzymes can be activated by the presence of chemicals, pH acids and even pH alkalinity, the change of the medium is what gives the enzyme permission to start with its reaction effect.
Usually this happens with enzymes that must be controlled, and that their activity must be in certain periods so as not to generate pathologies or even destroy a tissue of the organism.

Mitochondria have highly folded inner membrane that increase the membranes surface area for atp production. What concept does this illustrate?
1) a cell ability to maintain homeostasis is critical for life
2) catalysts speed up chemIcal reactions in cells
3) all livIng things are composed of cells
4) a cells structure is related to its function
Mitochondria have a highly folded inner membrane that increases the surface area for ATP production. This explains that a cell's structure is related to its function. So the correct answer is option 4.
What is the role of mitochondria in a cell?In an eukaryotic cell, the mitochondria are present and produce ATP through the Krebs cycle, the electron transport chain, and other cellular processes. The inner membrane of mitochondria is folded, and this membrane consists of many complexes that are required for the electron transport chain.
Due to the transfer of electrons, a proton gradient is formed that allows the formation of ATP. More complexes (ATP synthase) can fit into the membrane as it folds, and ATP production increases. To produce more energy, the mitochondria are made this way. Apart from this, other organs such as the intestine have villi that are highly folded to increase the rate of absorption.
Hence, the shape of each cell is related to its function. Option 4 is true for the statement.

Characteristics of asthma include:___________.a. Chronic inflammatory disorderb. Airway hyperresponsivenessc. Alveolar collapsed. Genetic susceptibilitye. Airway remodeling
Answer:
The correct answer is a.
Explanation:
Asthma is characterized by a chronic inflammatory process of the airways in which a variety of cells predominate, such as eosinophils, neutrophils, and mast cells. Chronic inflammation produces an increase in airway reactivity and recurrent episodes of wheezing, respiratory distress, intercostal pulling, coughing, and chest tightness, especially at night and in the morning. Asthma is a disease in which there is bronchial hyperresponsiveness, which is an exaggerated response of the bronchial mucosa and leads to bronchospasm and bronchitis.
