What type of rock is pictured here?

Answers

Answer:

intrusive

Explanation:

The  type of rock that is pictured here is intrusive rock

What is intrusive rock?

Igneous rock known as intrusive rock, sometimes known as plutonic rock, is created when magma is driven into older rocks at a depth in the Earth's crust. The resulting rock slowly hardens below the surface of the Earth, however erosion may eventually expose it. Numerous types of rocks are formed by igneous intrusions.

See extrusive rock as well. Magma that has permeated pre-existing rock and crystallized and solidified underground can create intrusions like volcanic necks, sills, batholiths, and laccoliths. One of the two ways igneous rock can develop is by intrusion. Extrusion, like that of a volcanic eruption or other similar event, is the other.

Answers

Ratio of height to weight, this is also otherwise known as BMI index.
Final answer:

A range of healthy body weight relies on a variety of factors including the ratio of height to weight (BMI), skinfold measurements (body fat percentage), and ratio of waist to hips (fat distribution measurement).

Explanation:

The factors typically used to determine the range of a healthy body weight include the ratio of height to weight, skinfold measurements, and the ratio of waist to hips.

The ratio of height to weight is also known as Body Mass Index (BMI). It is a useful measure to check if your weight is in a healthy range for your height. This is calculated by dividing your weight in kilograms by the square of your height in meters.

Skinfold measurements are taken to measure body fat percentage. Fat is pinched and measured using calipers at various parts of the body, and a formula is used to calculate body fat percentage.

The ratio of waist to hips or waist-hip ratio (WHR) is a measurement of fat distribution. It helps to identify if more fats are stored around your waist or hips, which could raise your risk for some health problems.

when are amino acids used instead of gluecose

Answers

Final answer:

Amino acids are used as an energy source instead of glucose in situations of carbohydrate and fat deficiency, such as fasting or starvation. They are converted into intermediates that enter the Krebs cycle for ATP production, but this can lead to muscle wasting and tissue damage if prolonged.

Explanation:

Amino acids are typically utilized for protein synthesis and other nitrogenous substances like nucleotides, rather than as a primary energy source. However, in situations where there is a deficiency of carbohydrates and fats, such as during fasting or starvation, amino acids can be mobilized as an alternative source of energy. This is because amino acids can be converted into metabolic intermediates that enter the Krebs cycle, leading to the production of ATP.

In normal conditions, glucose is the preferred energy source, and amino acids are reserved for growth and repair processes. Yet, during periods of prolonged fasting or insufficient caloric intake, the body can resort to breaking down proteins into amino acids for energy, which can lead to muscle wasting and tissue damage if persisted for extended periods. This shift happens because the body has no mechanism to store excess amino acids; they must either be used for protein synthesis or be catabolized for energy and excretion.

Answer:

Answer for third question.

Explanation:

The permanent destruction of forests to use the land or trees is known as deforestation. Deforestation takes place due to a number of reasons like natural causes and human activities. The main cause for deforestation is  overpopulation. Overpopulation results in an increase in global needs which leads to expansion of infrastructures, industries, agricultural needs and thus deforestation. Other reasons for deforestation are infrastructure expansion , logging for wood based industries, farming, mining etc. Deforestation causes drastic changes in the environment. The environmental problems which results from widespread deforestation include climatic changes, loss of biodiversity, flooding, increase in greenhouse gas emission, acidic oceans, air and water pollution etc.  Deforestation results in global warming.  Planting trees reduce the effects of deforestation by preventing soil erosion and pollution. The other ways to lessen the effects of deforestation includes recycling and using of recycled products. Reduce the usage of paper and use wood alternatives like hemp, bamboo, wood composites etc for construction and remodeling products. Also we can raise awareness in the community against deforestation through campaigns

How do the particles move in active transport?

Answers

In active transport particles move by making use of energy in the form of ATP.

Explanation:

Unlike in passive transport particles have to move against the concentration gradient in active transport. Thus particles require energy to do so and this energy is in the form of ATP. Osmosis and simple diffusion are examples of passive transport where substances move from a region of high concentration to a region of low concentration.

This movement is down the concentration gradient. In active transport particles move from a region of low concentration to a region of high concentration which is against the concentration gradient. Active transport is of two types.

In the first type called primary active transport energy is directly used in the form of ATP. In the second type called secondary active transport an electrochemical gradient created by ATP is used to facilitate the transport.

Hunter-gatherers:

Over hunting species leads to extinction (especially species like giant sloths, giant bison, mastodons, cave bears, saber-toothed cats)

Agricultural Revolution:

Flora and Fauna became domesticated  Habitats were destroyed because the grasslands forests and wetlands were replaced by farmland that results in erosion and floods and made the soil less fertile

Industrial revolution  

Artificial substances replaced raw animals and plant products (plastics, pesticides) The rate of pollution increased.

Final answer:

The hunter-gatherer lifestyle did not heavily impact the environment, whereas the Agricultural and Neolithic Revolutions led to changes in land use, social organization, and significant environmental manipulation. The Industrial Revolution further transformed human activity with mass production, causing notable increases in atmospheric CO2 levels.

Explanation:

Throughout history, the way humans have interacted with their environment has dramatically evolved. The hunter-gatherer societies had minimal impact on the environment as they fitted seamlessly into ecological food chains. However, the advent of the Agricultural Revolution around 3000 B.C.E. introduced permanent tools and farming tactics like crop rotation and the use of waste as fertilizer, paving the way for larger human settlements, trade, and increased environmental manipulation.

The Neolithic Revolution signified a pivotal shift from hunter-gatherer lifestyles to agriculture, leading to larger populations, specialization of labor, and sophisticated settlements such as Jericho and Çatalhöyük. This transition necessitated changes in land use, social organization, wealth accumulation, and even religious practices. However, not all societies embraced farming due to environmental unsuitability or perceived disadvantages.

The Industrial Revolution brought about significant changes in production, leading to widespread environmental impacts including an increase in global atmospheric carbon dioxide concentration. This remarkable era transformed human activity and initiated the mass manufacture of goods, which had global repercussions, shifting the world into a new ecological era.

1. How did Hubble determine that the Universe is expanding?

Answers

Answer:

.

Explanation:

Edwin Hubble discovered the expansion of the Universe by combining observations of galaxy distances with the redshifts seen in their spectral lines, implying their recession due to the expanding fabric of space, known as Hubble's Law.

Edwin Hubble determined that the Universe is expanding by studying the distances to galaxies and their spectral lines. He observed a correlation known as Hubble's Law, which stands for the concept that galaxies further away from us are moving away at greater speeds. When he combined measurements of distances with the observed redshifts in the spectral lines of these galaxies, he effectively applied the Doppler Effect, which suggested that these galaxies were receding from the Milky Way. The redshift of the spectral lines indicated that as the light from these galaxies travels to us, it stretches, correlating with the idea of the universe's expansion. This pattern of the galaxies' recession velocities being proportional to their distances laid the foundation for the belief in an increasing scale of space itself, akin to marks on an inflating balloon moving apart from each other. This was revolutionary in our understanding of the cosmos and laid the groundwork for modern cosmology.

In labrador retrievers some puppies have pink nose and some have black labrador retrievers with black for almost always have black noses what type of inheritance pattern is this explain how this is possible?

Answers

Answer:

Complete dominance.

Explanation:

In complete dominance, the two alleles interact in such a way that in heterozygosis the expression of one of them is phenotypically "visible" (the dominant), while the other is hidden (recessive). The heterozygote is phenotypically identical and indistinguishable from the dominant homozygote.

There are two pairs of better known genes that control the color of the Labrador's coat. The "B" gene is dominant and responsible for the black coat color, the "b" gene is recessive and responsible for the chocolate coat color. The "e" gene is responsible for the color of the yellow coat, and for this reason it must always appear homozygous (ee), which will inhibit the expression of the other gene pair. So the possible genotypes for the black coat are the following BBEE, BBEe, BbEE, BbEe, the possible genotypes for the chocolate coat are bbEE, bbEe, and the genotypes for the yellow coat are BBee, Bbee, bbee. So if the mating is done with two double heterozygous animals (BbEe) you can have puppies of the three coat colors in the litter.

However, if complete dominance occurs, the puppies will be black with a black face, because the gene for these characteristics is dominant. In that case, there was complete dominance.

What part of the blood closes a wound?
A. Plasma
B. Hemoglobin
c. Platelet
D. Capillary

Answers

The part of the blood that closes a wound is platelet and the correct option is option C.

Platelets are small, disk-shaped blood cells that play a crucial role in the clotting process. When a wound occurs and blood vessels are damaged, platelets are immediately activated and form a clot to close the wound and prevent excessive bleeding.

The process begins with platelets adhering to the exposed collagen fibers of the damaged blood vessel walls. This adhesion is facilitated by specific receptors on the platelet surface. Once adhered, platelets undergo a series of changes, releasing chemical signals that attract more platelets to the site of injury.

As platelets aggregate, they form a plug that seals the damaged blood vessel. In addition to their adhesive and aggregating properties, platelets release clotting factors, such as thromboxane and fibrinogen, which promote the formation of a fibrin meshwork. The fibrin meshwork strengthens the platelet plug and traps red blood cells, creating a stable blood clot.

Thus, the ideal selection is option C.

Which of the following is a natural cause of carbon increases and decreases?
Question 2 options:


clearing of land for new development


collecting and burning natural gas


plant growth related to weather


water usage related to fires

Answers

The natural cause of carbon increases and decreases is plant growth related to weather, which is influenced by natural weather patterns affecting the carbon cycle. In contrast, human activities such as burning fossil fuels and deforestation are major contributors to the rising levels of CO2 and other greenhouse gases. Hence, the correct option is c.

The natural cause of carbon increases and decreases referred to in the question is plant growth related to weather. This process is part of the carbon cycle, where plants absorb carbon dioxide (CO2) from the atmosphere during photosynthesis, which decreases atmospheric carbon levels. Conversely, when plants die and decompose, or when they are consumed by animals, the carbon is eventually released back into the atmosphere, leading to an increase in carbon levels. Natural factors such as weather can influence plant growth significantly, causing fluctuations in carbon uptake and release.

On the other hand, human activities such as the burning of fossil fuels, deforestation, and cement production are among the major contributors to the increase in greenhouse gas levels, particularly CO2. These activities disrupt the natural carbon cycle and have been linked to global climate change. Slash-and-burn agriculture, and the clearing of land for new development, are examples of human activities that directly contribute to the increase in CO2 concentration in the atmosphere.

Answers

Answer:

Earth's atmosphere is divided into five main layers: the exosphere, the thermosphere, the mesosphere, the stratosphere and the troposphere.

Explanation:

A spaceship departing from Houston, Texas, to Mars will move through the troposphere, stratosphere, mesosphere, and thermosphere, in that order, before entering the exosphere and finally leaving Earth's atmosphere.

The spaceship launched from Houston, Texas, aiming for Mars will pass through four main layers of Earth's atmosphere. These layers are distinct in terms of their composition and physical properties as the spaceship ascends from the Earth's surface into space.

Troposphere: The first layer above the Earth's surface where weather phenomena occur, extending up to about 8 to 15 kilometers.Stratosphere: This layer is above the troposphere, reaching up to about 50 kilometers. It contains the ozone layer, which absorbs and scatters the solar ultraviolet radiation.Mesosphere: The third layer extends from the stratosphere up to about 80 kilometers. Here, the temperature decreases with height, and it's where meteors burn up upon entering Earth's atmosphere.Thermosphere: The fourth layer, starting from about 80 kilometers and extending into space. The temperature increases with height due to the absorption of highly energetic solar radiation.

After exiting the thermosphere, the spaceship will transition through the exosphere, where the Earth's atmosphere merges into interplanetary space. Each layer presents unique challenges and phenomena as the spaceship ascends, providing a fascinating journey from the Earth to the cosmos.

Two processes form a cycle when the output from one process is the input for the other process, and vice-versa. Explain why respiration and photosynthesis form a cycle. Refer to specific types of molecules in your answer.

Answers

Explanation:

Photosynthesis produces glucose and O2 from inorganic CO2, light energy and water.

6CO2 + 6H20 + (energy) → C6H12O6 + 6O2

These end products, namely O2 and glucose are then used in respiration...

C6H12O6 (glucose) + 6 O2 → 6 CO2 + 6 H2O + ≈38 ATP

The CO2 and H2O produced as waste in respiration can then be incorporated at the beginning of photosynthesis. Thus the reactions are cyclic- they feed into each other.

 

Further Explanation:

Photosynthesis is a chemical pathway that’s integral to producing energy in plants and other primary producers. Energy in the form of molecules of glucose is produced from light, water and carbon dioxide while oxygen is released. This occurs in several complex steps, photosynthesis is a rate limited reaction, depends on several factors including carbon dioxide concentration, ambient temperature and light intensity; the energy is retrieved from photons, I.e. particles of light, and water is used as a reducing agent. This occurs in the thykaloids, where pigment molecules like chlorophyll reside.

Occuring in several complex steps, photosynthesis is a rate limited reaction, depends on several factors including carbon dioxide concentration, ambient temperature and light intensity; the energy is retrieved from photons, I.e. particles of light, and water is used as a reducing agent. Water supplies the chlorophyll in plant cell with replacement electrons for the ones removed from photosystem II.

Additionally,

water (H2O) split by light during photolysis into H+ and OH- acts as a source of oxygen along with functioning as a reducing agent; it reduces the molecule NADP to NADPH by providing H+ ions and produces molecules of the energy storage molecule ATP through an electron transport chain. This occurs in the thykaloids, where pigment molecules like chlorophyll reside. Later, in dark reactions, NADP and NADPH are used in the Calvin cycle where monosaccharides or sugars like glucose are produced after the modification of several molecules. These store energy in their bonds, which can be released in respiration in the mitochondria.

In all eukaryotic cells mitochondria are small cellular organelles bound by membranes, these make most of the chemical energy required for powering the biochemical reactions within the cell. This chemical energy is stored within the molecule ATP which is produced. Respiration in the mitochondria utilizes oxygen for the production of ATP in the Krebs’s cycle via the oxidization of pyruvate( through the process of glycoysis). The electron transport chain, in which oxygen functions as the terminal electron acceptor occurs in both plants and animals.

Glycolysis: occurs in the cytoplasm 2 molecules of ATP are used to cleave glucose into 2 pyruvates, 4 ATP and 2 electron carrying NADH molecules. The Kreb's cycle: in the mitochondrial matrix- 6 molecules of CO2 are produced by combining oxygen and the carbon within pyruvate, 2 ATP oxygen molecules, 8 NADH and 2 FADH2. The electron transport chain, ETC: in the inner mitochondrial membrane, 34 ATP, electrons combine with H+ split from 10 NADH, 4 FADH2, renewing the number of electron acceptors and 3 oxygen; this forms 6 H2O, 10 NAD+, 4 FAD.
