Cells lining the gut need to take in glucose, but at a certain time, the concentration of extracellular glucose is lower than the concentration already stored in the cells. What process is needed here?.
Answers
Cells lining the gut need to take in glucose, but at a certain time, the concentration of extracellular glucose is lower than the concentration already stored in the cells. Active transport.
By using cellular energy, active transport involves transporting molecules across a cell membrane. Passive transport is an alternative to active transport that solely moves molecules using kinetic energy.High concentrations of substances the cell needs, like ions, glucose, and amino acids, are typically accumulated during active transport.Active transport examples include the uptake of glucose in human intestines and the uptake of mineral ions into plant root hair cells.Active transportation is divided into two categories: Primary (direct) active transport entails using metabolic energy (such as ATP hydrolysis) directly to mediate transfer. Coupling a molecule with another while it travels through an electrochemical pathway is known as secondary (indirect) active transport.

i don't know
Answers
Answer:
The reaction in the diagram is right.
Explanation:
In complete combustion, hydrocarbon fuels burn in the presence of high concentration of oxygen that produces carbondioxide gas and water which are releases in the atmosphere. Complete combustion takes place only when there is oxygen present in large amount whereas incomplete combustion occurs when the oxygen in the environment is limited so complete combustion required more oxygen as compared to incomplete combustion.

what causes less competition
A. different reproductive habits of species
B. greater day/night temperature differences
C. greater differences between niches
Answers
Answer:
c
Explanation:
C. greater differences between niches.
A greater difference between niches results in less direct competition for resources. When species occupy different niches, their roles in the environment do not overlap significantly, and they can coexist with less interspecific competition. In contrast, if species have similar niches, they are in direct competition with each other, leading to reduced population sizes and potential extinction.
Different reproductive habits of species and greater day/night temperature differences have no direct effect on competition.

Introduction to punnett squares and alleles worksheet
Answers
A Punnett square is a diagram that is utilized to calculate the likelihood of an offspring inheriting a specific trait from its parents. This diagram is commonly used in the study of genetics and is named after its creator, Reginald Punnett.
Punnett squares utilize alleles, which are variations of a particular gene that can produce differing traits. Alleles are usually represented as letters, with uppercase letters representing dominant alleles and lowercase letters representing recessive alleles.
The Punnett square is made up of two axes, with the father’s alleles listed along the top and the mother’s alleles listed along the side. The possible combinations of these alleles are then shown within the squares of the grid. For example, if a father has an A allele and a mother has a B allele, their offspring could inherit an AB allele, an AA allele, a BB allele, or a BA allele.
Punnett squares are used to study a variety of genetic traits, such as blood type, eye color, and height, and can provide useful information about inheritance patterns.

The first permanent settlements may have been places for nomads to bury and honor their dead/places to house women & children/ tools, clothing, and containers
Answers
The first permanent settlements were likely established for various reasons, and the specific purposes may have varied among different societies and cultures. While it is difficult to determine the exact motivations behind these settlements, there are some common theories and factors that are often considered:
Resource AvailabilitySecurity and DefenseSocial and Cultural PracticesStorage and OrganizationDivision of LaborResource Availability: Permanent settlements may have been established in locations where resources such as water, fertile land, or abundant food sources were readily available. This would have provided a stable and sustainable living environment for early human groups.
Security and Defense: Settling in a particular location could provide protection and defense against potential threats, such as predators or rival groups. By establishing permanent settlements, early humans could create fortified structures or develop collective defense mechanisms.
Social and Cultural Practices: Early settlements may have served as places for various social and cultural practices. This could include burial sites or ceremonial grounds for honoring the dead or engaging in rituals. Settlements may have also housed specific groups within the society, such as women, children, or specialized artisans.
Storage and Organization: Permanent settlements would have allowed early humans to store and protect valuable resources, including tools, clothing, and containers. This would have facilitated the development of more complex societies and the ability to accumulate surplus goods.
Division of Labor: As settlements became more permanent, it is likely that early humans began to specialize in different tasks and roles. Settlements could have provided the necessary infrastructure and environment for specialized labor, such as agriculture, tool-making, or craftsmanship.
It is important to note that the purpose of the first permanent settlements would have likely evolved and expanded over time as human societies became more complex and developed. The exact reasons behind the establishment of these settlements can vary based on cultural practices, environmental factors, and the specific needs and goals of early human groups.

Which describes the two ways that energy is measured?
in convection and in temperature

in radiation and in convection
in wavelength and in temperature
Answers
Answer:
The answer is D. In wavelength and temperature
Explanation:
can I have brainiest Please
Energy is the ability to do work, and it is measured in two ways: in temperature and in wavelength. Temperature is a measure of the average kinetic energy of the molecules in a substance, and is typically measured in degrees Celsius or Kelvin.
What is Wavelength?Wavelength, which is commonly expressed in nanometers (nm), is a measurement of the separation between two adjacent points in a wave pattern.
The average kinetic energy of the molecules in a substance is measured by thermometers to determine temperature. This is accomplished by measuring a material's thermal expansion during heating or contraction during cooling.
The molecules have more kinetic energy at higher temperatures. Temperature is an important factor in convection, which is the transfer of heat energy from one place to another through the movement of fluids or gases. Wavelength is measured with spectroscopy, which is the study of the interaction of light with matter.
Spectroscopy is used to measure the wavelength of light, which is the distance between two successive points in a wave pattern. Wavelength is an important factor in radiation, which is the emission of energy in the form of electromagnetic waves. Radiation is the main way that energy is transferred from one place to another in space.

Shay creates a wave that has a frequency of 20 waves every ten seconds. How does the energy that her wave carries compare to a wave that has a frequency of 5 waves every ten seconds? Justify your response.
Answers
A frequency which produce 20 waves every ten seconds has more frequency and less wavelength than that which produces 5 waves every ten seconds.
What is Frequency?Frequency is the number of waves that pass through a fixed place in a given period of time. So, if the time taken for a wave to pass is 1/2 second, the frequency is 2 per second. If it takes 1/100 of an hour, the frequency will be 100 per hour.
The frequency of 20 waves every ten seconds can be simplified as 2 waves produced per second.
The frequency of 5 waves produced every ten seconds can be simplified as 1 wave produced every two seconds or 1/2 wave produced every second.
Therefore, the frequency of first wave is more than the second wave and the wavelength of first wave is less than the second wave as wavelength is inversely proportional to the frequency of wave.

Si el genoma de una especie contiene un 40% de la base timina, ¿cuál será el porcentaje de guanina del genoma de esta especie? 10% 35% 60% 30% 20%
Answers
Respuesta:
El porcentaje de guanina del genoma de esta especie será del 60%.
Explicación:
El genoma de todas las especies está compuesto por ADN (ácido desoxirribonucleico) bicatenario, lo que significa que tiene dos cadenas. Estas cadenas se unirán la una con la otra mediante un componente muy importante en los nucleótidos: las bases nitrogenadas que pueden ser de 4 tipos distintos: timina (T), guanina (G), adenina (A) y citosina (C). Los nucleótidos se aparean siempre de la misma manera para formar pares de bases: citosina con guanina (C-G) y adenina con timina (A-T). De esta manera, podemos inferir que si hay un 40% de base timina en el genoma de una especie, se unirá con un 40% de adenina, y el 60% restante serán pares C-G.
