In your own words, explain why photosynthetic cyanobacteria were likely the first organisms to survive and thrive in the harsh conditions on early Earth.
Explanation:
cyanobacteria are aquatic and photosynthetic, that Is they live in the water, and can manufacture their own food.Because they are bacteria, they are quite small and usually unicellular, though they often grow in colonies large enough to see.they have the distinction of being the oldest known fossils more than 3.5billion years old, in fact! it may surprise you then to known that the cyanobacteria are still around,they are one of the largest and most important group of bacteria on
In dogs, one pair of alleles determines coat color (dark and albino). Another pair of alleles determines hair length (short and long). Thus, each gamete will contain one of the coat-color alleles, C or c and one of the hair-length alleles, B or b. In repeated crosses of a specific dark, short-haired dog with an albino, long-haired dog, all the offspring were dark with short hair, as shown in cross I. However, in subsequent crosses of another dark, short-haired dog with a dark, long-haired dog, the ratios shown in cross II below were obtained. In cross II, the genotype of the dark, short-haired parent is which option choice.
Answer A: CcBb
Answer B: ccbb
Answer C: CCBB
Answer D: CCbb
Answer E: ccBB
Answer:
the answer is b
Explanation:
In cross II, the genotype of the dark, short-haired parent is which option choice. Answer A: CcBb
Genetic crossesIn genetic crosses, the allelic combinations that translate the phenotypes are called genotypes, and thus, the designations aa, Aa and AA represent the genotypes. In crosses of single-gene inheritance, in which there are dominance relationships, two different genotypes (Aa and AA) reproduce the same phenotypes. And when a cross occurs, both phenotypic and genotypic proportions can be observed.
With this information, we can conclude that the genotype in the second cross was heterogametic.

Draw the structure of ATP molecule and explain how it is formed
ATP is formed from the breakdown of glucose molecule in mitochondria of the cell.
ATP molecule is formed in the process of respiration i.e. aerobic and anaerobic. During aerobic cellular respiration, glucose reacts with oxygen in the mitochondria of the cell, forming ATP that can be used by the cell in different cellular activities. When glucose reacts with oxygen, three molecules are formed i.e. ATP, Carbon dioxide and water. ATP is used by the cell whereas the Water and carbon dioxide molecules are waste materials which are removed from the cell so we can say ATP is formed from the breakdown of glucose molecule in mitochondria of the cell.Learn more about ATP here: https://brainly.com/question/893601

Complete the sentence. Carbon flows between ____________, environmental storage centers that absorb and store carbon for long periods of time.
plants and animals
humans and air
rocks and soil
carbon sinks
Carbon is transfered by plants and animals.
Carbon flows between plants and animals, environmental storage centers that absorb and store carbon for long periods of time. Thus, the correct option is A.
What is Carbon cycle?Carbon cycle is one of the main biogeochemical cycles which has four main steps. In this first, carbon enters into the atmosphere as CO₂. CO₂ is absorbed by the autotrophs such as green plants for photosynthesis. Then, the animals consume plants as food, thereby, incorporating the carbon into their system. Afterwards, animals and plants die, their bodies decompose and the carbon is reabsorbed back into the atmosphere.
In this, plants use carbon dioxide for photosynthesis. Through this, they remove the inorganic carbon from the atmosphere and incorporate it into the plant's tissues in the form of sugars such as glucose, sucrose and starch. Animals get carbon by eating the plants or by hunting other animals.
Therefore, the correct option is A.

Why is the metric system more scientific than the English system?
A. The English system is older than the metric system, and so it is less relevant.
B. The English system is only used in English-speaking countries.
C. The English system was based on human traits, while the metric system was founded on physical constants.
D. The English system must be converted to the metric system using conversion factors.
Answer:
Unlike the British Imperial System, the metric system, or SI (from the French Système International), is based on a natural constant.
Explanation:
The metric system is more scientific than the English system because the English system was based on human traits, while the metric system was founded on physical constants.
What do you mean by the Metric system?The metric system may be defined as the scientific way of measuring weights, and distance in kilograms and meters respectively with the help of a decimal system.
The metric system may also be known as the SI system. SI system is not based on the human traits rather then it depends on the natural constant. It is more precise, standard, and easy to understand.
Therefore, the correct option for this question is C.

Wetlands are areas of standing water.
What is a swamp? A swamp is a forested wetland. Swamps are considered to be transition zones because both land and water play a role in creating this environment.
What are mangroves? Mangrove swamps (swamps are wetlands) are coastal wetlands found in tropical and subtropical regions.
What are bogs? A bog or bogland is a wetland that accumulates peat as a deposit of dead plant materials – often mosses, typically sphagnum moss.

The chloroplast is the organelle of a plant cell that makes the process of photosynthesis possible.
Photosynthesis refers to the metabolic reactions by which plant cells synthesize simple carbohydrates (glucose) by using the light energy from the sun and carbon dioxide.Photosynthetic reactions can be divided into light-dependent reactions and light-independent reactions.During photosynthesis, light-dependent reactions occur in the thylakoid membranes of chloroplasts.In conclusion, the chloroplast is the organelle of a plant cell that makes the process of photosynthesis possible.
