What types of organisms have mitochondria
Answer:
sup ._.
Explanation:
The mitochondrion (/ˌmaɪtəˈkɒndrɪən/, plural mitochondria) is a semi autonomous double-membrane-bound organelle found in most eukaryotic organisms. Some cells in some multicellular organisms may, however, lack mitochondria (for example, mature mammalian red blood cells). A number of unicellular organisms, such as microsporidia, parabasalids, and diplomonads, have also reduced or transformed their mitochondria into other structures.

Explain why reintroducing wolves changed the ecosystem of the park?
WILL GIVE BRAINLIEST
Answer:
After 70 years without wolves, the reintroduction caused unanticipated change in Yellowstone's ecosystem and even its physical geography. ... The healthier bear population then killed more elk, contributing to the cycle the wolves started.
Explanation:
The reintroduction of wolves had several positive effects on the ecosystem.
What are the effects of reintroduction of wolves?The reintroduction of wolves caused a trophic cascade of events in the Yellowstone national park. This resulted in an increase in the population of beavers and also brought back several forms of vegetation.
The killing of wolves in the 1930s resulted in the shifting of predatory pressure on the elk population. But, they were much less active in winter. They browsed on cottonwood plants and aspen.
But now, the predatory pressure came back on wolves. This keeps the elks more active. This also resulted in an increase in vegetation.
The reintroduction of wolves also resulted in the increase in the population of beavers because of the recovery of willow strands reflourished due to the activeness of the elk.
Therefore, the reintroduction of the wolf population greatly impacted the ecosystem of the Yellowstone national park causing a ripple of positive effects.

When a pinecone is open, it disperses its seeds. Based on your experiment, can you tell what weather conditions are needed for pine trees to release their seeds? Explain your answer.
Answer:
If a pine seed finds the right micro-climate, it will eventually sprout and a pine seedling will start to grow. However, pine seeds are usually released in a dormant state, which is most often broken by cold stratification. As a result, a pine seed will not sprout until the following spring when warm weather and some spring moisture are present.

Answer:
You can actually apply the same concept, obviusly you want the cars to be the same weight, and you want your cars to be not too fast, because of the same equation F=MA if the car is faster, is because it has higher acceleration, wich results in higher impact force.

Explain how the electron transport chain makes ATP.
Answer:
t
Explanation:
While Glycolysis and the Citric Acid Cycle make the necessary precursors, the electron transport chain is where a majority of the ATP is created. The Electron Transport Chain makes energy ... At the end of the chain the electrons are taken up by oxygen molecules to make water. This is why oxygen is known as the final electron acceptor.
Answer:
Explanation:
during electron transport, energy is used to pump hydrogen ions across the mitochondrial inner membrane, from the matrix into the intermembrane space. A chemiosmotic gradient causes hydrogen ions to flow back across the mitochondrial membrane into the matrix through ATP synthase, producing ATP

Which of the following can occur because of the exchange of homologous chromosome parts during the process of meiosis?
Answer:
Muttation can occur during the exchange of genetic meterial from homologous chromosomes which may led to cause deseases in some cases.
Explanation:
Homologous chromosomes exchange genetic material during the process of meiosis.
What is Meiosis?Meiosis is a type of cell division in which germ cells present in the sexually-reproducing organisms produces the gametes, such as sperm or egg cells. It involves two rounds of division which results in four cells with only one copy of each chromosome.
These four cells are haploid in nature. Meiosis produces the sex cells or gametes like eggs in females and sperm in males.
Meiosis is divided into nine stages. These are divided between the first time the cell divides (meiosis I) and the second time it divides (meiosis II).
Thus, homologous chromosomes exchange genetic material during the process of meiosis.
