Identify the stages of the cell cycle using the drop-down menus. Label A-E
Picture attached
Answer:
A - G1 phase
B - G2 phase
C - S phase
D - Mitosis
E - Interphase
Explanation:
Interphase is all the parts of the cell cycle excluding mitosis, and encompasses G1, S, and G2 phases. Cells spend most of their lives in interphase
G1 is the first gap phase, where the cell is growing and making checks in preparation for mitosis. During S phase (the synthesis phase), the DNA is replicated. This is so a full copy of the DNA can be passed on to the daughter cells.
During the G2 phase, the final checks are made before the cell undergoes mitosis, which is where the cell divides.
Answer:
A. G1 phase
B. S phase
C. G2 phase
D. Mitosis
E. Interphase

How can our lack of ecological understanding harm us?.
Answer:
Lack of understanding ecology has led to degradation of land and environment which is home to other species thus leading to extinction and endangerment of species because of lack of knowledge e.g. dinosaurs ,mammoth, white shark ,black rhinos , sperm whales etc.
Also Know, why is it important for humans to study the ecosystem? The study of ecosystem is important for Environmental Conservation, Resource Allocation, reduce pollution and destruction of ozone layer. It provides information about the benefits of environment and judicious use of Earth's resources in ways that make the environment healthy for future generations.
Lack of ecological understanding will result in natural resource degradation including things like soil erosion, deforestation, wildlife extinction, energy shortages, damage to marine ecosystems, and depletion of mineral resources.
What is ecological understanding?A subfield of research called ecology includes the areas of human science, population, neighborhood, ecosystem, and biosphere.
Ecology refers to the study of organisms, the environment, and the interactions between organisms and their surroundings.
The main objective of an ecologist is to increase their understanding of the life processes, habitats, interactions, and biodiversity of species.
Therefore, Lack of ecological knowledge can lead to natural resource degradation, which encompasses issues like soil erosion, deforestation.

What type of biological molecule is an exonuclease.
Answer:
Enzyme (protein)
Explanation:
Exonucleases are enzymes that catalyze the removal of nucleotides in either the 5-prime to 3-prime or the 3-prime to 5-prime direction from the ends of single-stranded and/or double-stranded DNA. Removal of nucleotides is achieved by cleavage of phosphodiester bonds via hydrolysis.

Biodiversity is key for the stability of ecosystems Explain why biodiversity is so important in an ecosystem.
Answer:
Variety of life is also called biodiversity The number of species of plants, animals, and microorganisms, the enormous diversity of genes in these species, the different ecosystems on the planet, such as deserts, rainforests and coral reefs are all part of a biodiversity.
why is it important
Declining biodiversity is a concern for many reasons.
1)A larger number of plant species means a greater variety of crops
2)Greater species diversity ensures natural sustainability for all life forms
3)Healthy ecosystems can better withstand and recover from a variety of disasters.
4) Provides biological resources such as Food , Medicinal resources and pharmaceutical drugs , Wood products , Ornamental plants , Breeding stocks, population reservoirs , Future resources , Diversity in genes, species and ecosystems
5) Ecosystem services as Protection of water resources and soil , Nutrient storage, Pollution breakdown
Explanation:
Biodiversity is important in ecosystems because it prevents the extinction of species, allows organisms to adapt to changes in the environment, and provides a wide range of materials and foods for survival. The number of species of plants, animals, and microorganisms, the enormous diversity of genes.

What types of cells perform photosynthesis
Answer:
Photosynthetic cells are quite diverse and include cells found in green plants, phytoplankton, and cyanobacteria. During the process of photosynthesis, cells use carbon dioxide and energy from the Sun to make sugar molecules and oxygen.
Explanation:
i hope this helps :)
Green plants, phytoplankton, and cyanobacteria all have cells that can synthesize oxygen.
Thus, Photosynthetic cells are highly diverse. Cells create sugar molecules and oxygen during the process of photosynthesis by using carbon dioxide and energy from the sun.
Chloroplasts, specialized cells present in plant cells, are principally responsible for photosynthesis.
The cells of the leaves of plants, notably the specialized structures known as mesophyll cells, are where photosynthesis mostly takes place within plant cells. Numerous chloroplasts, where photosynthesis occurs, are present in the mesophyll cells.
Thus, Green plants, phytoplankton, and cyanobacteria all have cells that can synthesize oxygen.

The independent variable is the one that causes a response in the dependent variable. Option C. the Sun and the temperature outside
What is an independent variable?Refers to all the variables in an experiment that provoke a response in another variable.
An independent variable is the one that changes or is controlled and modified in the experiment to analyze how another variable responds to it. It changes to analyze its effects on the dependent variable.
What is a dependent variable?Refers to the variable, which response depends on any change in the independent variable.
It represents a quantity of something whose value depends on how the independent variable is modified. The change in the dependent variable might be proportional or inversely proportional to the change in the manipulated variable.
In the exposed example, the correct option is C. the Sun and the temperature outside.
The Sun ⇒ Independent variable ⇒ According to how its proximity fluctuates it provoke a temperature change.Temperature ⇒ Dependent variable ⇒ It depends on the Sun
