Living things obtain matter from their environment and release waste back into it. This matter moves in a cycle. Plants use air, water, nutrients, and sunlight to make food and grow. Some animals eat the plants and use their matter to grow. When those animals die, decomposers will grow using the matter from the animals' bodies. The decomposers release this digested matter back into the air and soil. The matter in an ecosystem is recycled. Gases are a type of matter that moves through an ecosystem. For example, oxygen and carbon dioxide are cycled between organisms and the air. The producer in the diagram takes carbon dioxide from the air. It uses this gas and water to make sugar, releasing oxygen as waste. Then the consumer breathes in the oxygen and uses it in its body. It also eats the producer for food, represented as carbon in the diagram. The decomposer takes oxygen from the air and food from the consumer or producer. The consumer and decomposer make carbon dioxide, putting it into the air. When producers use it again, the matter is recycled. Describe in words how carbon and oxygen move through an ecosystem. (my little bro needs help and I am to lazy to do it)
Answer:
"living things obtain matter from their environment and release waste back". plants use carbon dioxide, then let out oxygen for us to use. When animals die, decomposers release the digested matter back into the air and soil. Different types of gases move throughout a ecosystem and is recycled between organisms and air. (again going back to the air recycled between a plant and a human).
Answer:
the decomposers release carbon dioxide that help plans grow then they can do photosynthesis then the oxygen is given to animals then they die then decompose and that's a cycle

If purple flowers are dominant in a plant and white flowers are recessive in that plant, then when purple-flowered
plants with two dominant genes are mated with white-flowered plants with two recessive genes, the first
generation of offspring should have
A
100% white flowers
B
75% purple flowers and 25% white flowers
с
50% purple flowers and 50% white flowers
D
100% purple flowers
im pretty sure it would be c
If purple-flowered plants with two dominant genes are mated with white-flowered plants with two recessive genes, the first generation of offspring should have 100% purple flowers.
Genes are defined as units of inheritance that occur in the chromosomes. Usually, genes occur in pairs called alleles and these alleles control the expressed traits (phenotype) of an organism.
In this case, we have a flowering plant having a dominant gene for purple flowers (R) and a recessive gene for white flowers (r). Using a punnet square, we can see that the first generation will have all purple flowers since it is the dominant gene as shown.

Explanation:
oxygen aids in glucose production through respiration and supports the organism since glucose is the food for plants
The role of oxygen in photosynthesis and in cellular respiration - B Oxygen is released in photosynthesis and used in cellular respiration to produce energy.
Role of oxygen1. In photosynthesis, solar energy is harvested as chemical energy in a process that converts water and carbon dioxide to glucose. Oxygen is released as a byproduct.
6CO₂ + 6H₂O+ energy → C₆H₁₂O₆ + 6O₂
2. In respiration, the product of photosynthesis, glucose and oxygen are converted into carbon dioxide, water, and energy and oxygen is used to break down glucose
C₆H₁₂O₆ + 6O₂ → 6CO₂ + 6H₂O+ energy

label for the wavy arrow would be MOST USEFUL for communicating the role of
light in photosynthesis?
a. Light is radiated from the chloroplast during the light-independent reactions.
b. Light energy is cycled within the thylakoid.
c. The chloroplast reflects the green wavelengths of light.
d. Light is the energy source for converting ADP to ATP, and NADP+ to NADPH.
Answer:
There is no model in this question but the question can be answered based on the provided information and general knowledge of photosynthesis. The answer is:
d. Light is the energy source for converting ADP to ATP, and NADP+ to NADPH.
Explanation:
Photosynthesis, which is being described in this question, is the process by which autotrophic organisms synthesize their food in the presence of sunlight. The photosynthetic process occurs in the CHLOROPLAST. However, photosynthesis occurs in two stages namely: light dependent and light independent reaction.
Light dependent reaction occurs specifically in the THYLAKOID of the chloroplast where the photons of light is absorbed by chlorophyll molecule (photosynthetic pigment). The light energy that hits the chlorophyll makes it excited, hence, providing the energy to produce ATP from ADP and NADPH from NADP+.
These products are pivotal in the next stage of photosynthesis (light independent stage). Hence, light plays a very crucial role in photosynthesis by providing the energy source for converting ADP to ATP, and NADP+ to NADPH.

how does our water use affect the bay-delta ecosystem?
Answer:The Sacramento-San Joaquin Rivers Delta and San Francisco Bay (hereinafter “Bay-Delta”) is an important economic and environmental resource benefitting all of California and the nation. The Northern California Water Association (NCWA) and Sacramento Valley water resources managers recognize the importance to California’s future of a healthy Bay-Delta and providing high quality and reliable water supplies for all beneficial uses. For the past several decades, NCWA has been a strong and constructive participant in the various processes designed to help solve the challenges in the Bay-Delta. We will continue to play a constructive role in implementing necessary solutions to Bay-Delta problems, as long as the actions do not affect the ability to serve water for multiple beneficial uses in the Sacramento Valley, including cities and rural communities, fish, farms, birds and recreation.
NCWA and Sacramento Valley water resources managers have supported the state’s co-equal goals–providing a more reliable water supply for California and protecting, restoring and enhancing the Delta ecosystem–and have encouraged success in Voluntary Agreements as a new way forward in California.
What is the role of operons in prokaryote gene expression?
Blocks of DNA called operons are used to encode proteins that are required for a certain task or that are part of the same metabolic pathway.
What is operon?Operons are frequently found in bacterial genes. An operon is a collection of genes that all share a single promoter during transcription.
There are regulatory DNA sequences in every operon, and these sequences serve as binding sites for regulatory proteins that either encourage or inhibit transcription. Genes involved in lactose metabolism are found in the lac operon of E. coli. It only expresses itself when lactose and glucose are both absent.
A lactose sensor is the lac repressor. When lactose is present, it ceases to function as a repressor, blocking transcription of the operon in its usual state. Through its isomer allolactose, the lac repressor indirectly detects lactose.
Therefore, Blocks of DNA called operons are used to encode proteins that are required for a certain task or that are part of the same metabolic pathway.

How do scientists hope to limit climate change?
In what way is surface area more important for cells than volume?
Answer:
As a cell grows in size, the surface area gets bigger, but the volume gets bigger faster. Thinking about this as a ratio (division), the volume is the denominator and the surface area is the numerator. If the volume is getting very big, then the ratio itself will be getting very small.
