Answer:
The owl pellet must be ejected before the owl can eat again.
Explanation: When the pellet moves from the gizzard back up to the proventriculus to be regurgitated it blocks the owl's digestive system which stops them from eating new prey until the pellet is ejected from their body.

Which is one factor that adds to the greenhouse effect
Answer:
The gases that contribute most to the Earth's greenhouse effect are: water vapour, carbon dioxide, nitrous oxide, methane and ozone. The contribution that a greenhouse gas makes to the greenhouse effect depends on the amount of it that it is the atmosphere and how much heat that particular gas absorbs and re-radiates.
Explanation:
Answer:
An increase in gases in the atmosphere that absorb heat
Explanation:
Greenhouse gases such as CO2, can trap heat and alter our climate and to some extent cause the greenhouse effect.

give two reasons that the wolf population is not at Hardy-Weinberg equilibrium
Answer:
HW equilibrium means no selective pressures. Selective pressures change the relative frequencies of the alleles in the gene pool. It also means the population does not have either immigration or emigration to change the ratios of alleles in the gene pool
The Hardy-Weinberg principle of genetic equilibrium tells us what to expect when a sexually reproducing population has no selection pressure, no gene flow, no nonrandom mating, not even genetic drift
Explanation:
The wolf population is not considered in a Hardy-Weinberg population as the population of wolves always remains in the state of migration, and there will be an occurrence of natural selection. For a population to be in a Hardy-Weinberg equilibrium there should be no migration and events of natural selection taking place
Pacemakers maintain the heartbeat in people who suffer from certain defects. The function of an artificial pacemaker is to send electrical impulses that will contract the heart muscles and regulate the pumping of the heart. Which condition could be corrected by a pacemaker?
slow heart rhythm (bradycardia)
Explanation:
when a persons heart beat is not normal is typically let's say 60-100 beats per minute that means the blood is not pumped properly throughout the body. so the pacemaker works as an heart machine to keep your heart beating.
How is a job in fish and wildlife management different from one in forestry?

Which of the types of cells in T. adhaerens contain cilia? (Choose all that apply)
gland cells
cylinder cells
fiber cells
cover cells
Answer:
Its Gland cells, Cylinder cells, and Cover cells
Explanation:
Cells like Gland cells, Cylinder cells, and Cover cells contains cilia in T. adhaerens.
What is T.adhaerens?Trichoplax adhaerens is one of the three named species in the phylum Placozoa. They have two cellular layers: the top epitheloid layer is made of ciliated (cover cells) flattened toward the outside of the organism, and the bottom layer is made up of cylinder cells that possess cilia used in locomotion, and gland cells that lack cilia.
Moreover, trichoplax generally has a thinly flattened, plate-like body in cross-section around half a millimetre, occasionally up to two or three millimetres. The body is usually only about 25 µm thick.
Therefore, these colorlessly gray organisms are so thin they are transparent when illuminated from behind, and in most cases are barely visible to the eye.

Select ALL of the molecules that are
produced in cellular respiration and are reactants in photosynthesis.
Answer:
6Carbon Dioxide (CO2) + 6Water (H2O) + energy
Explanation:
The products for cellular respiration are the same as the reactants in photosynthesis. Each process is dependent upon the other. The results/products of cellular respiration are 6 carbon dioxide molecules and 6 water molecules along with the releasing of energy. In photosynthesis energy is absorbed in cellular respiration energy is a byproduct.

what specific actions or events affect climate change in the sahara desert
Answer:
In the future, the Sahara and Sahelian regions could experience more rainfall than today as a result of climate change. Wetter periods, termed African humid periods, occurred in the past and witnessed a mesic landscape in place of today’s hyperarid and semiarid environment. Such large past changes raise the question of whether the near future might hold in store similar environmental transformations, particularly in view of the growing human-induced climate, land-use, and land-cover changes. In the last decades, geoengineering initiatives (in the form of active re-greening projects of the Sahara and Sahel) have been proposed and could have significant effects on the climate of the region. Here, we synthesize the literature on past and projected changes in the hydroclimate of the Sahelian-Saharan region and the associated feedbacks. We further address the current state of knowledge concerning Saharan and Sahelian afforestation projects and their consequences. Our review underscores the importance of vegetation in land-atmosphere-ocean feedback processes and the far-field impacts of northern African ecosystem changes.
