Answer:
C. H+ ions do not accumulate inside the thylakoid, so ATP synthase makes too little ATP.
Explanation:
Plant withering refers to the virtual death of plant cells due to lack of food. During the light-dependent reactions of photosynthesis, ATP needed for the synthesis of sugar (food) is created in the thylakoid membrane of the CHLOROPLAST of plant cells.
In the light-dependent reaction, hydrogen ions (H+) builds up/accumulate in the thylakoid lumen to create an electrochemical or proton gradient i.e. a difference in the concentration of H+ ions across the membrane. The hydrogen ions passes through a protein complex called ATP synthase, which forms ATP from ADP (by adding phosphate group), from the energy generated by the electrochemical gradient formed as a result of hydrogen in (H+) build up.
Hence, a plant that possess leaky membrane due to the cold temperature will likely wither because H+ ions are not able to accumulate inside the thylakoid causing a proton gradient, so ATP synthase makes too little ATP.

While savannas and temperate grasslands are both types of
grasslands and share many characteristics, they also have
some differences. Compare them below by writing each
characteristic in the correct location. You will use each only
once.
• home to many types of grazers
• experience all seasons of weather
• home to bison
• home to the African elephant
• example: tallgrass prairies of North America
• example: Serengeti in Tanzania
• also known as tropical grasslands
• few trees due to little rainfall
1)
(Savannas)
(Both Types of
Grasslands)
(Temperate
Grasslands)
Answer:
S - Savannas are typically found in tropical or subtropical regions.
S - Savannas tend to have more trees and shrubs.
S - Savanna's climate is drier than that of a grassland.
G - Grasslands are found in temperature regions.
G - Temperature Grasslands are mainly devoid of trees, receive less rainfall than Savannas & endure broader temperature extremes.
G - Grasslands make up 25 percent of the Earth's land surface and dominate in regions with limited rainfall, which prevents forest growth. This results from nearby mountain ranges that cause rain shadows over adjacent open-range lands.
B - Both represent the world's richest and most diverse ecosystems. They both provide a home for a quarter of the world's population and a habitat for thousands of plants and animals.
B - Many species gather in vast numbers, graze on the varied grasses, and can be found nowhere else on Earth. The coexistence between wildlife and grasses is key to healthy ecosystems. Animal migrations regenerate the landscapes, by controlling pests, dispersing seeds, and trampling invasive species. Through this partnership, grasslands and savannahs generate vital benefits for both people and nature.
B - Ecosystems such as these two in specific are essential for climate mitigation – they store carbon, locking it deep in the soil and extensive root systems. They are the source of or support many of the world’s biggest rivers and wetlands, ensure food security, support livelihoods, and are embedded in the cultural identity of millions of people.
(Also, A savanna or savannah is a mixed woodland-grassland<---similarity)
Explanation: Just research. I decided to state 3 characteristics for both The Savanna and The Grasslands, and then 3 for "B" (both).
Which of the following is NOT one of the major land biomes? a. tropical rain forest c. temperate grasslands b. temperate savanna d. temperate deciduous forest
Answer:
Temperate Savanna.
Explanation:
Savanna is not temperate, it is also called tropical grasslands, further supporting my answer. It is PART of the kinds of grasslands, So because it is a part, it is not a major Biome.
Temperate savanna is not the major land biomes.
What is Biomes?Some of the electrons in metallic atoms are held there quite loosely. As a result, they frequently lose electrons and generate cations. In contrast, most nonmetallic atoms have a stronger attraction to electrons than do metallic atoms, and as a result, they gain electrons to form anions.
As a result, when two atoms from a metallic and a nonmetallic element unite, the nonmetallic atoms usually tend to take one or more electrons from the metallic atoms and create ions.
One-third of the Earth is covered in forests, which are primarily made up of trees. A large portion of the terrestrial biodiversity of the planet, including insects, birds, and mammals, is found in forests.
Therefore, Temperate savanna is not the major land biomes.

Label the Big Dipper, Little Dipper, and indicate the Polaris.
The Polaris lies in a direct line with the Earth's rotational axis, which is "above" the North Pole (north celestial pole). Its stands almost motionless in the sky, and all the stars of the northern sky appear to rotate around it. The attached image is a clear indication.
How can we describe the Polaris location in the sky?The Polaris appears to remain stationary in the sky while all other stars appear to rotate around it. To locate Polaris in the sky, one must first find the Big Dipper, which is a well-known group of seven stars that resemble a ladle or dipper. If one follows the two stars at the end of the bowl of the Big Dipper, they will point directly to Polaris.
Once located, Polaris can be used as a guide to determine one's direction when navigating at night. Because it is very close to the celestial north pole, its position in the sky is directly above the Earth's geographic North Pole. This makes it a reliable reference point for navigation in the Northern Hemisphere.

State the functions of the skeletal system, including the number and the major bones in the human skeleton.
The skeletal system serves several important functions in the human body. These functions include:
1. Support: The skeleton provides the structural framework for the body, giving support and shape to the organism.
2. Protection: The skeletal system protects vital organs such as the brain, spinal cord, heart, and lungs. For example, the skull protects the brain, the ribcage protects the heart and lungs, and the vertebrae protect the spinal cord.
3. Movement: Bones act as levers for muscles, enabling body movement. The skeletal system works in conjunction with the muscular system to facilitate motion.
4. Mineral storage: Bones store essential minerals, such as calcium and phosphorus, which are necessary for various body functions.
5. Blood cell production: Red and white blood cells, as well as platelets, are produced in the bone marrow, which is found in some bones.
6. Energy storage: Yellow bone marrow, found in the medullary cavity of long bones, stores energy in the form of fat.
The human skeleton consists of 206 bones in adults. Some of the major bones include:
1. Skull: Comprised of the cranium and facial bones, it protects the brain and supports the structures of the head.
2. Spine (vertebral column): Consists of 33 vertebrae, which protect the spinal cord and support the upper body.
3. Ribcage: Includes 12 pairs of ribs, the sternum, and the thoracic vertebrae, which protect the heart and lungs.
4. Humerus: The long bone in the upper arm, connecting the shoulder to the elbow.
5. Radius and Ulna: The two bones in the forearm, connecting the elbow to the wrist.
6. Femur: The long bone in the thigh, connecting the hip to the knee, and is the longest bone in the body.
7. Tibia and Fibula: The two bones in the lower leg, connecting the knee to the ankle.
8. Pelvis: A basin-shaped structure that supports the spine and organs of the lower abdomen, and connects the spine to the lower limbs.
These are just a few examples of the major bones in the human skeleton.
Answer:
Explanation:skeletal system functions are diffrent of types . In addition to defining our shape and traits as humans, it:
enables movement: Your skeleton helps you stand and move by supporting your weight. Your bodily components are movable thanks to the cooperation of joints, connective tissue, and muscles.
Bone marrow, which makes blood cells, is found in bones. The bone marrow makes RBC AND WBC
supports and shields organs: Your ribs shield your heart and lungs, your backbone shields your spine, and your skull shields your brain.
Mineral storage: Your bones are where your body stores minerals like calcium and vitamin D.

A pedigree chart is used to _______.
predict percentage of offspring with a trait
predict genotypic probabilities
track inherited traits through generations
identify the genotype of parents
A pedigree chart is used to track inherited traits through generations.
A pedigree chart is a visual tool that represents the inheritance patterns of specific traits or genetic conditions within a family. It helps to trace the occurrence of traits, diseases, or genetic conditions across multiple generations by depicting the relationships between individuals and their affected or unaffected status.
Pedigree charts are commonly used in genetics and genetic counseling to analyze patterns of inheritance, identify carriers of genetic disorders, determine the probability of passing on certain traits or diseases, and study the transmission of traits within families. By examining the patterns of inheritance in a pedigree chart, one can gain insights into the mode of inheritance, such as autosomal dominant, autosomal recessive, or X-linked inheritance, and make predictions about the likelihood of certain traits or conditions appearing in future generations.

25 PTS MIGHT GIVE BRAINLIEST Imagine that you are a grain of pollen on a flower that cross-pollinates
the flower of another plant of the same species. Write a journal
entry in complete sentences describing your journey. Correctly
include each of these terms in your entry: pollinator,
pollen, pistil, stamen, anther, stigma, ovary, and eggs
Answer:Pollination is the transfer of pollen grains from an anthers to a receptive stigma. In most species of flowering plants, external agents bring about pollination. Also, flowers have evolved special structures and mechanisms to ensure successful pollination.
There are two types of pollination
--> Self pollination: This takes place when mature pollen grains from the anther of a flower fall on the stigma of the same flower or that of another flower on the same plant. This type of pollination brings the male gametes and egg cells of the same plant together. The resultant offspring show very little genetic variation.
--> Cross pollination: This occurs when mature pollen grains of a flower are transferred to the stigma of a flower of another plant of the same or closely related species. This brings the male gametes and egg cells of two different parent plants together. Therefore, there is greater genetic variation among the offspring.
Explanation: i hope this can give you a little push!
Answer:
As a grain of pollen on a flower, I am responsible for cross-pollinating the flower of another plant of the same species. I began my journey on the stamen of one flower, where I picked up the pollen from another. I was carried to the pistil of the next flower and deposited the pollen on the stigma. I then traveled down the style to the ovary, where I fertilized the eggs, commencing the production of the next generation of this flower.
