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.

- Nitrogen fixation (N2 to NH3/ NH4+ or NO3-)
- Nitrification (NH3 to NO3-)
- Assimilation (Incorporation of NH3 and NO3- into biological tissues)
- Ammonification (organic nitrogen compounds to NH3)
- Denitrification (NO3- to N2)

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.

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.

how do red blood cell,muscle cells and nerve cells differ from a typical animal cell
Answer:Red blood cells carry a specific type of protein, called hemoglobin, which is able to bind oxygen and release it in other tissues. A nerve cell doesn't have this protein because it doesn't need to bind oxygen. Instead, the nerve cell uses other proteins that help it transmit signals to other cells.

7.10(A) Increased human populations can lead to the depletion of locally available
resources within communities. Compared to other communities, which of these locally
available resources is most likely to be depleted in desert communities?
A. Mineral
B. Oxygen
C. Gasoline
D. Water
Answer:water
Explanation:
In comparison with other communities, the locally available resource which is most likely to be depleted in desert communities is: D. water.
What is a desert?A desert can be defined as an extremely dry area of land that is characterized by sparse vegetation, especially due to very low rainfall and precipitation.
Generally, the amount of water available for plants and other living organisms in all deserts is usually very little (low).
In conclusion, we can infer and logically deduce that water is the locally available resource which is most likely to be depleted in desert communities.

Khi hai đám mây tích điện trái dấu lại gần nhau, hiệu điện thế giữa chúng có thể lên tới hàng triệu vôn. Giữa hai đám mây có hiện tượng phóng tia lửa điện và ta trông thấy một tia chớp. Vài giây sau ta mới nghe thấy tiếng nổ, đó là sấm (do vận tốc ánh sáng nhanh hơn vận tốc của tiếng động nên ta trông thấy tia chớp trước). Khi đám mây dông tích điện đi gần mặt đất tới những khu vực trống trải, gặp một vật có độ cao như cây cối, người cầm cuốc xẻng… thì sẽ có hiện tượng phóng tia lửa điện giữa đám mây và mặt đất. Đó là hiện tượng sấm sét.

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.
Explanation:
Fun facts:
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.
How does astronomical data support the Big Bang Theory?
The collected astronomical data taken by the scientists support the Big Bang Theory.
Hubble is a scientist which find out the age of the universe with the help of law which also called Hubble's law that allowed astronomers to calculate the time period at which the galaxies start moving apart. This calculation provides an estimate when the Big Bang happened as well as provides information about the age of Universe. Hubble calculated that the Universe was about 2 billion years old so we can conclude that big bang event occur about 2 billion years ago.
