Why does crab grass do so well when ordinary grass struggles in late summer? Is this a phenomenon ? Or is this based on a scientific principles, what is it that causes crab grass to thrive in relation to the different type of plants ?
Crab grass does so well when ordinary grass struggles in late summer
because its seed germination is higher when exposed to hotter
temperatures.
The seeds of crab grass are mostly dormant and their germination is
dependent on the soil temperature. During summer, the temperature of the
soil is usually higher which aids its growth .
This therefore explains the reason why crab grass does well than ordinary
grass in late summer periods.

Answer:
alcoholic fermentation/ anaerobic respiration
Explanation:
Alcoholic fermentation is a biochemical process in which sugars such as glucose, fructose, and sucrose are converted into small amounts of ATP, producing ethanol and carbon dioxide during the process. ... In this form of anaerobic respiration, pyruvate is broken down into ethyl alcohol (C2H6O) and carbon dioxide

He placed biotic factors in first but needs to add some abiotic factors, two abiotic factors could he add Sunlight and Water.
What are abiotic factors in an ecosystem?An ecosystem is a place where biotic factors (that have a life) and abiotic factors (that have no life) converge, for the balance of the ecosystem both are necessary.
For example, in an ecosystem, animals and plants are the biotic factors, and among them, there are relationships such as animals that feed on other animals or others that feed on plants. But this life would not be possible if there were no factors such as water, sun, soil, oxygen, among others. So, the correct answer is C.

Epidemiology studies health-related states and occurrences (not simply diseases) in specific communities.Therefore, option (A) is correct.
What is epidemiology?The study and analysis of the distribution, patterns, and determinants of health and disease conditions in a given population is what epidemiology is all about. It is one of the most important aspects of public health, and it influences both policy decisions and evidence-based treatment by determining the factors that put people at risk for disease and setting goals for preventative medical care.
Descriptive, analytical, and experimental methods are the three primary approaches utilized in epidemiology. Descriptive epidemiology is the method that is utilized the most to investigate the occurrence of disease, despite the fact that all three can be employed to do so.
Therefore, option (A) is correct.

how long does it take for a photon to travel through the convection zone
Answer:
50 million years
Explanation:
It can take a photon as long as 50 million years to travel all the way through the radiative zone. The convection zone surrounds the radiative zone. In the convection zone, hot material from near the Sun's center rises, cools at the surface, and then plunges back downward to receive more heat from the radiative zone.
Cell membranes are made up of a bilayer of phospholipids that are very selective about what substances can pass through.The table below shows the different types of molecules that can enter a cell. It compares the concentration on the outside to the inside of the cell, its relative size, and whether it is polar, nonpolar, or an ion. Determine how each molecule can pass into the cell. Is it by passive transport, active transport, or endocytosis? (3 points)
Answer:
Answer: Oxygen = passive Carbon Dioxide = passive Fructose = Endosytosis glutamine = Active Sodium ion = Active Potassium ion = Active Protein molecule = Passive or Endocytosis
Explanation:
js trynna get points lol
The molecules can pass into the cell by passive transport, active transport, or endocytosis.
Molecule | Concentration Outside | Concentration Inside | Size | Polarity | Transport | Mechanism
Glucose High Low Small Polar Diffusion
Oxygen High Low Small Nonpolar Diffusion
Sodium High Low Small Ion Active transport
Chloride Low High Small Ion Active transport
Amino acids Low High Medium Polar Carrier-mediated transport
Large protein Low High Large Polar Endocytosis
Glucose and oxygen can pass into the cell by diffusion. Diffusion is the movement of molecules from an area of high concentration to an area of low concentration. Glucose and oxygen are both small molecules, and they are both polar. This means that they can dissolve in the phospholipid bilayer of the cell membrane.
Sodium and chloride can pass into the cell by active transport. Active transport is the movement of molecules from an area of low concentration to an area of high concentration. Sodium and chloride are both ions, which means that they are charged particles. This means that they cannot dissolve in the phospholipid bilayer of the cell membrane. Instead, they need to be transported across the membrane by special proteins called ion pumps.
Amino acids can pass into the cell by carrier-mediated transport. Carrier-mediated transport is a type of passive transport that uses carrier proteins to transport molecules across the cell membrane. Amino acids are polar molecules, but they are larger than glucose and oxygen. This means that they cannot simply diffuse across the cell membrane. Instead, they need to be transported across the membrane by carrier proteins.
Large protein can pass into the cell by endocytosis. Endocytosis is a process by which the cell engulfs large molecules or particles. The cell membrane forms a pocket around the molecule or particle, and then the pocket pinches off to form an endocytic vesicle. The endocytic vesicle then fuses with a lysosome, where the molecule or particle is broken down.

Division of cells resulting in the development of an embryo from a zygote happens after fertilization. Therefore, option "A" is correct.
What is fertilisation?The creation of a single cell known as a zygote by the fusion of a female gamete is egg and a male gamete a sperm. The biological process of fertilization in animals entails the union of a sperm as the male gamete and an egg as the female gamete or ovum.
The three techniques of internal fertilization are oviparity is an egg deposited outside of the female body, oviparity is an egg kept within the female, and viviparity is said to be developed within the female followed by live delivery.
Therefore, fertilization is the first step in the development of the zygote and the development of life.
